摘要
通过对感应电动机动态电磁关系的分析,引出了感应电动机的数学模型和在M-T坐标系上的数学模型表达式,指出了感应电动机的模型是一多变量、强耦合的非线性系统。将模糊控制技术应用于感应电机的变频调速中,设计了一种转速模糊控制器,并用MATLAB/Simulink对基于模糊控制的感应电机矢量控制系统进行了仿真。仿真结果表明:对于感应电机来说,模糊控制器的控制性能优于常规的PID控制器。
By analyzing induction motor′s dynamic electromagnetism,it has listed the induction motor′s mathematics model and the equation on M-T coordinate in this thesis.And it has indicated that the induction motor′s mathematics model is a multi-variable,strong coupling,nonlinear system.In this thesis,fuzzy control is applied to variable-frequency regulating speed of the induction motor,where one kind of fuzzy controller of speed is designed.Then the vector control system made up of fuzzy controller is simulated by MATLAB/Simulink.The simulation results show that its performance is better than that of general PID controller.
