摘要
电动汽车PMSM在电机起动过程经常出现调节器饱和现象,时间越长会导致电机的动、静态性能越差。对出现饱和现象的原因进行分析,提出一种解决起动过程中调节器饱和的有效方法。该方法在传统双环矢量控制基础上,增加电压截止负反馈并结合状态反馈线性化,实现电流间的动态解耦,解决起动过程中电流调节器饱和问题。仿真实验验证了该方法的可行性和有效性,实现了调速范围、速度跟踪性能及动态响应等电机的综合性能的提高。
The saturation phenomenon is ususlly happned to the regulator in the start-up procedure of electric vihicles＇ permanent magnet synchronous motor, and the dynamic and static performance of the motor will be worse and worse while the phenomenon lasts longer. The causes of saturration phenomenon was analyzed, and an effective method was proposed to solve the saturation of the regulator during the startup process. Based on the traditional double loop vector control, the method could increased the voltage cut-off negative feedback and combined the state feedback linearization to realize the dynamic decoupling between the current and solved the saturation problem of the current regulator during the starting process. The feasibility and effectiveness of the method are verified by simulation experiments, and the comprehensive performance of the motor is improved by speed range, speed tracking performance and dynamic response.
