Electropneumatic servodrives control for positioning task

This paper considers the problems of control of an electropneumatic servodrive for translational positioning task. A simplified dynamic model of the rodless cylindrical actuator system controlled by proportional servovalve is given. Two models are presented: one is the nonlinear model which can be used in the simulation study of dynamic behavior of the electropneumatic servodrives and the other is the linearized model which can be used for preliminary synthesis of the closed-loop control system.The control strategy with the state feedback controller has been used. A simulation example which gives the comparison of system behavior with a state feedback controller and classical PID controller has been made.
