摘要

For the optimal control problem of induction motor in field-weakening control,the paper introduced the optimal current distribution method of induction motor in field-weakening region.The result of Matlab/Simulink simulation verifies the optimal current distribution method has better effect of field-weakening control than traditional 1/ωr field-weakening method.The field-weakening control of the optimal current distribution method is realized under experiment platform based on TMS320LF2407A,which proves field-weakening control effect of the method is better than the traditional field-weakening method.%针对感应电动机在弱磁控制时的最优控制问题,介绍了感应电动机弱磁区的最佳电流分配法；在Matlab/Simulink环境下进行仿真,仿真结果验证了最佳电流分配法较传统的1/ωr法具有更好的弱磁控制效果;在基于TMS320LF2407A的实验平台上,通过实验实现了最佳电流分配法的弱磁控制,也验证了该方法的弱磁控制效果优于传统弱磁法.
