Motor Parameter Estimation and Maximum Ratio of Torque to Current Control Research

基于空间矢量控制原理,通过在不同的交直轴电流分配策略下控制永磁同步电机,利用实验数据估算电机参数,并根据估算参数实现了电机的最大转矩电流比控制。实验过程与相应的仿真结果表明,该方法估算的电机参数可用于电机最大转矩电流比控制,能得到较好的控制效果,具有一定的工程实际意义。

Based on space vector control principle,control of permanent magnet synchronous motors by differentd- q axis current allocation policy,used experimental data to estimate the motor parameters so as to achieve themaximum ratio of torque to current control. Experimental procedure and simulation results show that this methodwhich estimate the motor parameters can be used to the maximum ratio of torque to current control,the control effectcan be better,has some practical engineering.
