摘要:
用于伺服系统的永磁同步电机,一般具有较小的转动惯量,可能使得电机的机械时间常数小于电磁时间常数。电流环在动态过程中不能有效抑制反电动势的扰动,电流的动态响应明显变差。为了减小反电势在转速动态过程中对电流环产生的扰动,两对比研究2种不同的补偿方法:改进电流环控制器的方式和在电流调节器输出处对反电动势进行的补偿方式。在仿真研究基础上,确定采用反电动势补偿方式进行实验。实验结果验证了当电机惯量较小时加入补偿措施后可以使电机在恒加速时反馈电流无差的跟随给定电流指令。
Abstract:
In servo system,permanent magnet synchronous motor(PMSM) generally has small inertia,which could make the electromechanical time constant less than electromagnetic time constant.Face with such situation,the current loop in a dynamic response cannot resist the disturbances of back-electromotive-force(BEF),and dynamic responses of current deteriorate sharply.In order to reduce the disturbances of current loop by BEF in the speed dynamic process,comparative research studied two different compensation methods:i...
