摘要
目的设计一种模糊自整定PID参数的智能控制器,消除异步电机转速冲击.方法根据异步电机的调速特点,提出和设计一种模糊控制算法,基于MATLAB编制仿真程序,嵌入到PID控制器中,进行了仿真对比试验.结果对模糊自整定PID参数方法进行的分析和仿真结果表明,该模糊PID控制器能迅速消除系统余差,改善普通控制器的性能;既具有PID控制器高精度的优点,又具有模糊控制器快速、适应性强的特点.结论该模糊控制器是一种智能控制器,应用到异步电机转速控制系统中,使系统取得良好的响应;并能有效地减少系统超调量.
The purpose to design intelligent controller of fuzzy self-adjusting PID parameter is to eliminate the effect caused by the speed of AC asynchronous,which comes from the variety of parameters.Based on the character of Asynchronous motor,analysis and simulink of the way have been done.The result proves that the controller can steady state error of the system and improve the performance of ordinary PID controller.It possesses both the precise character of PID controller and the flexible advantage of fuzzy controller,and can guarantee that the regulation system has good dynamic and static quality,meanwhile reduce overshort.
