Abstract Linear motor is generally used as the driving device in high precision situation, but the traditional PID control is difficult to meet the accuracy demand and the dynamic response of the motor. In this paper, based on the combination of fuzzy self-tuning PID control and two degree of freedom PID control, a new PID self-tuning controller with 2-DOF based on target value filtering is proposed. And Matlab/Simulink model has been built to simulate the controller. The simulation result shows that: comparing with traditional PID control and fuzzy self-tuning PID control ,by using this controller,both the dynamic performance and response speed has been advanced,and the maximum deviation is decreased as well,which verified the feasibility of the design.
