| 摘 要： | 交流异步电动机具有很强的非线性特性,因此在调速控制中控制器的参数很难达到最优化.采用矢量控制后交流电机的调速性能可以和直流电机媲美.但变频交流电机矢量控制系统存在3个PI环,同时交流电机本身具有很强的非线性.由此可知调节3个控制器的参数使系统的调速性能达到最优存在很大的困难.文中建立了电机的仿真模型,在此基础上采用遗传算法对转速闭环控制器的参数进行了优化,并将优化的控制器参数与非优化的控制器参数的控制效果进行了仿真对比,结果表明取得了良好的效果.

| Abstract: | AC motor has strong non-linear characteristics.As a result,the optimize of the control can be realized very difficultly in the speed control.The performance of speed regulation of AC motor can compare with that of DC motor after the FOC(field orientated control) is introduced into AC motor field.But there exit three PI loops in FOC system,and AC motor has strong non-linear characteristics,as a result,there exits great difficult when regulating the parameters of three controllers to optimize performance of s... |
