参数自调整PID模糊控制器及在数字随动系统中的应用

PID Fuzzy Controller With Auto-tuning Scaling Factors And Its Application In Digital Servo Systems

结合传统PID的控制原理 ,介绍一种参数自调整的PID模糊控制器。开发了一套能在线调整PID参数的模糊控制方法的软件 ,并分别将它和传统的PID控制器作用到数字随动系统中。对二者的控制结果进行了比较。实验结果表明 ,参数自调整PID模糊控制器使系统稳态性能优良 。

By incorporating the conventional PID control theory,a PID fuzzy control with auto-tuning scaling factors is introduced.A set of software that can tune the scaling factors of the PID fuzzy controller on line was developed,this PID controller and traditional PID controller were applied to digital servo systems. The control results were compared.The results of experiment show that the PID fuzzy control with auto-tuning scaling factors has a good performance in steady state and can improve control accuracy.
