Abstract

In this paper, combining feed forward DMC and PID control algorithm is applied to the servo system of electric cylinder. Considering for the servo control system of electric cylinder, a PID controller based on dynamic matrix control (DMC) feed forward is designed with utilizing the quickness and adaptive characteristics of dynamic matrix predictive control by combining the DMC algorithm with PID controller, which could obtain online control for the servo control system of electric cylinder and realize the rapid and real-time control. Simulation results show that the servo control system of electric cylinder has better static and dynamic performance.
