Abstract

A robust control scheme for an electro hydraulic actuator is presented. A PID (Proportional - Integral - Derivative) controller is designed for controlling the position of the actuator in a wide range of physical uncertainties and external disturbances. The performance of the actuator variables is illustrated via simulations. In the future the present results will be applied to a real experimental system involving a double acting cylinder (Festo - model), with an electro hydraulic servo valve or an ON - OFF hydraulic valve where the PID controller will be realized in MATLAB environment with a Q4 Quanser card.
