| 摘 要： | 针对采用矢量控制方法的内置式永磁同步电机(IPMSM)存在解耦复杂、附加优化目标难以融入系统控制等问题,提出了一种基于最大转矩电流比(MTPA)的IPMSM转矩预测控制方法。在推导MTPA控制原理的基础上,分析了转矩预测的控制机理及性能指标函数。22 kW试验样机的仿真与试验结果表明,系统稳态及全局加减负载条件下调速性能良好、转矩动态响应迅速。该方法在重载条件下定子电流利用率显著提高,满足电动车辆驱动控制系统的性能和效率指标要求。

| Abstract: | Interior Permanent Magnet Synchronous Motor (IPMSM) adopting vector control method has decoupling complexity and difficulty of additional optimization goal integrated into system control, IPMSM torque predictive control method based on Maximum Torque per Current (MTPA) is proposed. On the basis of deducing MTPA principle, torque predictive control principle and performance index function are analyzed. 22 kW IPMSM prototype simulation and experimental results show that the system has good static and dynamic performance under load variation condition in full range of speed. The proposed method has higher stator current utilization rate under heavy load condition, and electric vehicle drive performance and efficiency index requirements are achieved. |
