摘要
为提高超磁致伸缩执行器控制系统的定位精度,提出了将模糊理论与PID理论相结合的复合控制算法,该算法将模糊积分作用引入传统模糊控制器,实现了模糊PID控制;在整个过程中的不同阶段采用不同的控制方式。利用P-模糊PID控制和传统模糊控制进行仿真实验,仿真结果表明:P-模糊PID控制在保持传统模糊控制优点的同时,改善了传统模糊控制的响应速度和灵敏度;P-模糊PID控制下的超磁致伸缩执行器响应迅速,无超调,控制精度高。
In order to improve the positioning accurary of controlling system for giant magnetostrictive actuator,compound control scheme is presented through the combination of fuzzy and PID.Fuzzy integral effect is introduced into the traditional fuzzy controller to achieve a fuzzy-PID control;the different control mode is applied to the various phases in the whole process.Control experiment is done with P-Fuzzy PID control and conventional fuzzy control.The simulation results show that P-Fuzzy PID maintain the advantages of the traditional fuzzy control,and improve its response speed and sensitivity.Meanwhile,the P-Fuzzy PID controller enables the system to be of good fastness,no-overshoot and very high accuracy.
