to maximize fuel economy [ 1 ]. Due to complex nonlinearities, it is difficult to find exact and reliable physical models. Therefore, the control of throttle valve system is a challenging problem and a robust controller is required to cope with built
with academic purposes in order to study feedback control in graduate and undergraduate courses. The ball and beam is a classic example of such system that can be used as benchmark. In the literature, a great diversity of methods can be found applied to
decades, different control techniques have been researched to increase the accuracy of joint motion control for exoskeletons. In [ 4 , 5 ] used a feedback and feed forward proportional–integral–derivative (PID) controller for monitoring the limb

has an extra degree of freedom represented by the fourth wheel. The dynamics model and control methodologies have been proven quite challenging, as many factors affect the mobile robot system. Friction, backlash in the wheels, nonlinear behavior of the
This study was completed to assess the efficacy of certain chemical inducers (potassium dihydrogen phosphate, potassium monohydrogen phosphate, oxalic acid, salicylic acid, sodium salicylate, ferrous sulfate and magnesium sulfate) compare to flusilazole fungicide against Sphaerotheca fuliginea, the causative fungus of powdery mildew of cucumber under greenhouse conditions. The impact of these elicitors on some biochemical and growth characters of cucumber was also examined. The data demonstrated that the flusilazole was the best treatment against powdery mildew followed by salicylic acid, potassium dihydrogen phosphate, magnesium sulfate, ferrous sulfate, oxalic acid and potassium monohydrogen phosphate, respectively. Marked raise in the measured biochemical parameters (chlorophyll content, peroxidase and polyphenoloxidase) of treated cucumber compare to untreated control. Growth and yield characters (plant height, number of fruits/plant and yield/plant) of cucumber were remarkably increased in cucumber treated with examined elicitors compare to untreated control. The examined chemical inducers could be counted as stand by for control powdery mildew of cucumber.
Introduction Controlling blood glucose levels remains a key factor to manage diabetes and prevent or delay the risk of micro- and macrovascular complications [ 1 ]. Regular self-monitoring of glycemia can be inconvenient in the long term (painful
feedback signal in the control system. The balancing of Segways, hover-boards and unicycles is performed by Proportional Integral Derivative (PID) in [ 1 , 3 , 4 ] or by fuzzy logic [ 2 ] controllers. The use of an optimal controller, i.e., a Linear
1 Introduction The quadcopter is one of the autonomous robot types that do not need a supporting surface; it contains four symmetric rotors. The symmetry of the quadcopter is crucial because the control of the quadcopter depends on rotor speed and
In this case study a fully symbolic design and modeling method are presented for blood glucose control of diabetic patients under intensive care using Mathematica. The analysis is based on a modified two-compartment model proposed by Bergman et al. (2). The applied feedback control law decoupling even the nonlinear model leads to a fully symbolic solution of the closed loop equations. The effectivity of the applied symbolic procedures being mostly built-in the new version of Control System Professional Suite (CSPS) Application of Mathematica have been demonstrated for controller design in case of a glucose control for treatment of diabetes mellitus and also presented for a numerical situation described in Juhász (8). The results are in good agreement with the earlier presented symbolic-numeric analysis by Benyó et al. (1).
