摘要
由于城市地铁的发展,具有体积小,牵引性能良好等优势的永磁电机正在逐步应用于轨道交通的牵引系统。针对直接对电机参数实测需要安装传感器或者估算精度的问题,将利用滑模变结构控制理论的滑模观测方法,实现对基于矢量控制的地铁永磁牵引电机的进一步优化,减少了传统中装传感器进行测量的麻烦,节约了成本。利用仿真,对滑模观测器的性能进行验证。结果表明:滑模观测器在地铁的永磁牵引仿真系统中有很好的鲁棒性,而且跟随效果良好。
Due to the development of the city subway, magnet motor with small size, good traction performance andother advantages is gradually applied to rail traction system. For installing sensors to measure the motor parameters and estimationaccuracy, the sliding mode observation method based on the corresponding theory is used to achieve further optimizationof vector control of subway traction permanent magnet traction motor(PMSG) from subway, and reduce the trouble of installingthe sensors. Through simulation, the performance of the sliding mode observer is verified. The results show that: sliding modeobserver has good robustness in subway PMSM traction simulation system.
