NONLINEAR PI COMPENSATOR FOR SERVOHYDRAULIC CONTROL

This paper considers the control of an electro-hydraulic servosystem (EHSS) for translational positioning using a nonlinear five-parameter PI compensator. A linear dynamic model of the system and the structure of the compensator are given. A simulation example of the system control has been made. The nonlinear PI compensator gives better results than the linear PI compensator during the transient response.
