基于电压闭环反馈的永磁同步电机弱磁调速研究
|
摘要
电动汽车对电机的调速范围要求较高,需要宽调速的控制技术。为扩大永磁同步电动机(PMSM)的调速范围,研究并实现了电压闭环反馈弱磁控制方法。该方法将电压利用率作为参考值构建电压环,通过电压反馈信号和给定指令信号计算弱磁电流的参考值i_(dref),从而有效提高PMSM的弱磁扩速。利用MATLAB/Simulink仿真平台搭建了表贴式PMSM弱磁控制系统。仿真结果表明系统有较宽的调速范围,而且区间转换平稳,具有良好的响应特性。
The actual operating conditions of electric vehicles were complicated,and the speed range and torque requirements of PMSM were higher. In order to improve the speed range of the built-in permanent magnet synchronous motor,the voltage closed-loop feedback field weakening control method was studied and realized. The method used the voltage utilization as a reference to construct the voltage loop,and the weak feedback was calculated by the voltage feedback signal and the command signal. Current idreference value,thus realizing the permanent magnet synchronous motor weak flux expansion. The simulation model of the field weakening control system of the built-in permanent magnet synchronous motor was established on the MATLAB/Simulink platform. The simulation results showed that the system had a wide speed range and the interval was smooth and had good response characteristics.
