摘　　要：直线电机在高精度直线运动场合作为驱动装置时,采用传统的PID控制难以满足精度和动态响应的要求。本文在结合模糊自整定PID控制和二自由度PID控制的基础上,提出了一种新型的基于目标值滤波型二自由度双模糊PID自整定控制器用以满足高精度场合下的直线电机控制。并通过Matlab/Simulink搭建了模型并进行了仿真,仿真结果表明:该控制器相比PID控制和模糊自整定PID控制具有更好的动态性能,具有较小的超调量和较快的响应速度,验证了设计方案的可行性。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 controUer,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.
