Abstract :
This paper focuses on improving PDF (Pseudo Derivative Feedback) controller and employing it in higher order follow-up system. By designing a circle-compensation, a novel PDF controller is proposed based on PDF control theory. Moreover, the improved PDF is compared to PID and traditional PDF through simulation using an approximated dynamic system model of a higher order hydraulic system, which consists of PLC, frequency converter, asynchronous motor, pump and pipe. The results show that the improved PDF controller provides satisfactory control performance in contrast with PID control strategy and traditional PDF controller in hydraulic system.
