Abstract

The objective of this paper is to present a proposed control model for the electromechanical damper mass spring system including the backstepping technique in comparison with the conventional proportional–derivative–integral (PID) controller unit to realize the best performance of the control systems. The suggested approach demanded the construction in laboratory arrangement of damper mass spring system which linked with electrical position sensor, and the theoretical work involved the derivation of the required mathematical equations in order to formulate the simulation models in Matlab software package. The obtained results show that the backstepping control technique provides the better performance associated with stable control system especially with increasing the value of selected mechanical load.

1 Introduction

In the recent decades, damper mass spring systems are widely used in different areas of engineering field applications. They have been applied in most dynamics suspension systems to provide more reliability of the design requirements such as increasing the factors of safety or absorbing the impact forces [1–2]. They can be categorized into passive and active mechanical elements, the passive control mechanical elements are represented by springs and dampers parts while active elements can be subdivided into various kinds of sensors and actuators equipment [3–4]. Actually many forms of electronic control devices have been inserted in some application of mechanical vibration control system in order to gain more sensible reduction in the measurement of vibration level. For that, the damper mass spring systems can be arranged in various control configurations to improve the behaviour of the employed control systems and to meet the required demands of the control application [5–8].

Besides, many researchers in a lot of literatures have been concerned with damper mass spring systems applications and carried out multiple theoretical and experimental studies. Some of these literatures focused on the study of the dynamic response characteristics of the mechanical elements in the applied system, while the others dealing with the analysis of control system depended on the related mathematical models in order to carry out the computer simulation process of the specified damper mass spring system [1–13]. The main purpose of this work is to attempt to use different controller models for selective electromechnical systems consisting of series combination of damper mass spring elements connected with position sensor. To realize this goal, two forms of controller units have been used; the first one is the classical proportional–derivative–integral controller (PID), while the other is the backstepping controller technique.

Backstepping represents as controller technique which can be applied for various dynamical systems to obtain a stable control model especially for nonlinear dynamical systems. In brief, the backstepping method refers to the control process that is based on the systematic and recursive design in application of feedback control model for various systems [13–16]. One of the merits of this technique is the ability to employ a new control Lyapunov function (CLF) for the selected control system that permits an analysis approach for the characteristics parameters of the closed loop system. Contrary to a lot of feedback linearization methods in which the problems of the precise model or cancellation of the useful nonlinear terms may occurr, the backstepping technique can permit a proper choice of designing tools for the purpose of accommodating of nonlinearities and it can be used to prevent the unwanted cancellation. The biggest advantage of the backstepping approach as compared with other control methods lies in its design flexibility merit according to its recursive use of Lyapunov functions [12–20]. The simulation process of the employed electromechanical control system will be run via Matlab software package based on the obtained physical parameters of the mechanical elements and the corresponding mathematical models. The step input response for each control model will be applied in simulation process and according to the outcoming simulation results; the comparisons will be done between the employed controller units by using different values of mechanical loads to observe the best response of each control model.

This paper has been organized as in the following. The construction and the mathematical models of the employed damper mass spring systems are introduced in Section 2. The controlled models of the suggested electromechanical system will be described in Section 3. The Matlab simulation process involving the displayed results are presented in Section 4 while Section 5 contained the conclusions.

2 The construction and mathematical models of the electromechanical system

The electromechanical system under consideration consists of damper, mass and spring elements beside electrical position sensor as shown in Fig. 1. In laboratory, the mechanical parts have been mounted vertically in series combination and connected in parallel configuration with electrical position which has been mechanically linked with the platform that carries the mechanical load. The electrical position sensor will be responsible to detect the mass displacement that occurs due to applying different values of mechanical load at the platform. The tolerance in the position of the platform will be measured with respect to the reference point that has previously been determined. Practically, the position sensor acts as a variable electrical resistance element which consists of movable iron core that provides a linear sliding motion and smooth contact with fixed resistance. It has a maximum value of electrical resistance equal to (530 Ω), while the stroke length of the iron core is equal to (250 mm) [9]. The sensor has been connected to electrical unit which has been designed to convert the different values of the tolerance in the position distance to the corresponding electrical voltage signals.

To obtain the corresponding mathematical models of the suggested electromechanical system, it will be required to obtain the required mathematical equations for the mechanical and electrical subsystems. For the mechanical subsystem, the Newton's law will be applied to obtain the net force as in the following [20–22]:
i=13fi=f1+f2+f3,
where
f1=md2xdt2,
f2=bdxdt,
f3=kx,
The mechanical subsystem consists of three kinds of elements, the first item is a mass (m), and the second one is a damped coefficient (b) and finally the spring constant (k). f1, f2 and f3 represents inertial, viscous and spring restoring forces and measured in (N). Therefore, the sum of the mechanical forces of the damper mass spring system can be calculated as in the following:
ft=md2xdt2+bdxdt+kx,
Equation (5) represents the mathematical model of the damper mass spring system under consideration in which the parameter (x) represents the displacement of mass that is measured from equilibrium position. Taking the Laplace transform for Eq. (5) under zero initial conditions, the transfer function of the applied mechanical system will be represented as shown in Eq. (6).
X(s)Ft(s)=1(ms2+bs+k),
For the electrical subsystem and according to the characteristics of the employed position sensor as variable resistance, the output voltage signal from the sensor unit can be determined as in the following [8, 9]:
Vsensor=Isensor×Rsensor,
In the employed electrical circuit Isensor=Itotal=VtotalRtotal, where
Vsensor=VT×RsensorRtotal,

Hence, to calculate the change of the movement x(t) with respect to time due to applied various values of mechanical load, the position sensor will send an electrical voltage signal proportional to the net of displacement in the system position.

3 The controlled models of the electromechanical system

The block diagram of the proposed controlled damper mass spring system is shown in Fig. 2.

The suggested approach of the electromechanical damper mass spring control system will be subdivided into the following control models:

  1. i)Control model with using PID controller unit

To maintain the required structure of the closed loop control system with using PID controller and unity feedback element, it is required to employ and calculate the following transfer functions [20–22]:

And (G1, G2 and GC) can be expressed as follows:
G1=1(ms2+bs+k),
G2=Vx,
GC=(Kp+Kis+Kds),
where

Taking GT = (GC)∗(G1)∗(G2)

Hence, the overall transfer function of the entire control system (Gsys) will be formed as follows [18]:
Gsys=GT(s)H(s)1+GT(s)H(s),
With taking unity feedback H(s) = 1, then
Gsys=V(Kds2+Kps+Ki)xms3+(xc+VKd)s2+(VKp+xk)s+VKi,
  1. ii)Electromechanical Control system based on Backstepping Technique

The backstepping control design can be illustrated for the damper mass spring control system with applying the following steps [10–14]:

Step 1

The mathematical differential equation of the suggested damping system is given by:
d2xdt2+(bm)dxdt+(km)x=(1m)u,
where (u) represents the external force.

The Eq. (14) can be rewritten as
mx¨=kxbx˙+u,
Rearranging Eq. (15) as follows
x¨=kmxbmx˙+1mu,
Hence
x¨=F(x)+g(t)u(t)+d(t),
where:
The tracking error can be defined as follows:
e1=(xdx),
Then, the tracing error derivative can be represented as follows:
e˙1=(x˙dx˙),
The first Lyapunov function will be taken as follows:
V1=12e1Te1,
And the derivative of the first Lyapunov function will become as
V˙1=e1Te˙1=e1T(x˙dx˙),
β=x˙d+k1e1,
Where k1 represents the positive constant.
If the virtual control is replaced with the desired value, then Eq. (21) becomes:
V˙1=k1e1Te10,

And e2=(x˙β).

Then e2=(x˙x˙dk1e1).

The sliding surface will be defined in terms of the error as:
s=e2=(x˙β)=(x˙x˙dk1e1),

Step 2

In this step of the backstepping control technique, the second Lyapunov function will be selected as follows [14–19]:
V2=V1+12sTs,
And
V˙2=V1+12sTs˙,
V˙2=e1T(e2λ1e1)+sT(F(x,t)+g(t)u(t)+d(t)x¨dk1e˙1,V˙2=e1T(e2λ1e1)+sT(F(x,t)+g(t)u(t)+d(t)x¨dk1e˙1,V˙2=λ1e1Te1+sT(e1+F(x,t)+g(t)u(t)+d(t)x¨dk1e˙1),

Step 3

The external disturbance will be assumed as unknown, then the backstepping control scheme in final control signal can be obtained as follows:
u=1g(t)(F(x,t)k2s+e1+k1e˙1x¨d),

4 Simulation process and results

The simulation process of the proposed controlled models for the damper mass spring has been carried out using Matlab software. It has been runt based on the practical measuring values of the stiffness coefficient for the employing spring as well as the damping factor of the dah pot. These parameters values are equal to 408.2 N/m for the spring coefficient and nearly a 17.889 Ns/m for the damping coefficient of the dash pot has [8].

In the practical work with using the laboratory test bench of damper mass spring system, it was found when applying mechanical load equal to 400 g the tolerance in the displacement will be equal to 5.5 mm with respect to equilibrium position and the corresponding measuring value of the electrical voltage signal sending from the position sensor will be equal to 470 mV.

This practical test procedure has been repeated with applying different values of mechanical load such as 800, 1,200 and 1,600 g and the obtained results for the net displacement of the damper mass spring system will be equal to 6.3, 7.2 and 8.1 mm, respectively. The related corresponding values of the voltage signals sending from the position sensor have been equal to 600, 730 and 870 mV [8].

Starting with running the simulation control model with conventional PID controller unit and taking arbitrary values of the gain factors such as Kp = 1, Kd = 1 and Ki = 1.

As a sample of calculation, we apply mechanical load equal to 400 g. The overall transfer functions of the damper mass spring controlled system (Gsys) as mentioned in Eq. (13) will be calculated as in the following:
Gsys=0.47(s2+s+1)0.0022s3+0.5683s2+2.7151s+0.47

It can be displayed the unit step response results for the employed controlled system with using conventional PID controller unit and applying various values of mechanical load as shown in Fig. 3.

The main characteristics of the step input response have been summarized as shown in Table 1.

According to the obtained results in Table 1, the performance of the response of the control system can be improved to become more acceptable. It will be tried to make a tuning process for the gain factors of the PID compensator unit via Matlab software program in order to get more convenience results for the main characteristics of the step input response for the employed controlled system. The tuning process of PID controller leads to gain overall transfer functions of the tuned damper mass spring controlled system as shown in Table 2.

The display of the step input results for the tuned control system with applying the selective range of the mechanical load will be obtained as shown in Fig. 4(a)–(d), respectively.

As mentioned in Fig. 4 with using the tuned PID controller unit, the response of the controlled system due to applying step input has been more acceptable but in the range of mechanical load value that lies between 400 and 1,200 g. It can be clearly observed that the system will be unstable and has very large value of steady state error at the effect of applying 1,600 g of mechanical load. The characteristics of the tuned controlled damping system are listed as shown in Table 3.

where (NaN); represents the undefined results and it is an abbreviation of ‘Not A Number’ in Matlab software package [22].

To make an improvement for the response of the controlled system, the backstepping control technique will be employed to test the best behaviour of the damper mass spring controlled system. In the procedure of applying the backstepping control scheme, Eq. (28) will be modified as follows:
u=1g(t)(tanh(F(x,t))k2s+e1+k1e˙1x¨d)

According to Eq. (29) and with taking (k1 = 30) and (k2 = 10), then the Matlab Simulink model of the controlled damper mass spring system using backstepping control technique will be constructed as shown in Fig. 5.

In Fig. 6, it was clearly observed that the response of the selected damper mass spring controlled system has been more accurate with zero values steady state errors than low value of stalling time equal to 0.53 s as in the case of applying mechanical load equal to 1,600 g, leading to give better performance of the proposed control system. In summary, the main characteristics of the backstepping controlled model with step input can be listed as shown in Table 4.

According to the resulting theoretical and practical outcomes, the following conclusions can be drawn:

  1. The design of controlled models for the selective dynamical system has involved the practical results of the empirical laboratory work as well as the mathematical models of the suggested configuration of the damper mass spring system.

  2. From the obtained simulation results it was found that the employed backstepping control technique can provide a more stable system, in comparison with the classical PID controller model especially when applying an extended value range of mechanical load.
