摘要

为解决新能源汽车永磁同步电机无位置传感器控制在全速域范围内稳定性不足的问题,提出一种基于高频信号注入的复合控制策略。仿真结果表明,该策略在 0~1500 r/min 全速域范围内,位置估算误差均小于 0.5°,转速波动幅度低于 2%,相比传统高频注入策略,低速起动稳定性提升 30%,高速抗干扰能力增强25%,可满足新能源汽车动力系统的动态性能要求。

Abstract

To address the issue of insufficient stability of position sensorless control for Permanent Magnet Synchronous Motors (PMSMs) in the entire speed range of new energy vehicles, a composite control strategy based on high-frequency signal injection is proposed. Simulation results show that within the full speed range of 0 to 1500 r/min, the position estimation error is less than 0.5°, and the speed fluctuation amplitude is lower than 2%. Compared with the traditional high-frequency injection strategy, the stability of low-speed startup is improved by 30%, and the anti-interference ability at high speeds is enhanced by 25%. The proposed strategy can satisfy the dynamic performance requirements of new energy vehicle power systems.
