摘要
针对异步电动机非线性的特点,考虑到传统PID控制难以对其进行有效的控制的问题。文中设计了一种模糊自适应PID控制器,并将这种控制器应用到系统的转速调节的环节中。利用Matlab的Simulink工具搭建了模糊自适应PID控制的异步电机的仿真模型。仿真实验结果证明了设计的优越性,模糊自适应PID控制下的系统超调变小,反应速度变快,与原先的PID控制方式相比提高了系统的稳定性、动态响应性能以及鲁棒性能。
In terms of nonlinear feature of asynchronous motor,it is considered difficult to adopt conventional proportional-integral-differential(PID)method to take effective control on the motor.A sort of controller via adaptive,PID and fuzzy method is then proposed and also applied to the speed regulation section.By using Simulink software tools in Matlab,a simulation model of fuzzy adaptive PID control for asynchronous motor is established.The computer simulation indicates the priority of the design which can be seen from that the overshoot and response of the system is reduced.The stability,dynamic responding and robust performance of the system are also improved comparing to the former control method of PID.
