基于DSP的内置式永磁同步电机控制系统设计

Design of IPMSM Control System Based on Digital Signal Processor

针对车用需求,推导了内置式永磁同步电机(IPMSM)数学模型,分析了IPMSM矢量控制原理,设计了基于数字信号处理器(DSP)的IPMSM控制系统,实现了转子位置和电流检测、转矩控制及通讯等功能。实验结果表明,在不同转速下该控制系统都能够对IPMSM进行有效控制,达到车用动力系统对电机输出功率的要求。

According to the demand of vehicle, the mathematical model of IPMSM was deduced, IPMSM control sys- tem design based on digital signal processor （DSP） was realized with some functions such as rotor position and current ac- quisition torque and speed control. Experimental results show that the system can control the IPMSM effectively at different speeds and achieve the power requirements of electric vehicles.
