摘要
为了提高直接转矩控制系统的性能 ,本文对影响直接转矩控制效果的定子电阻识别技术、低通滤波补偿技术进行研究。根据能量转换原则 ,推导出一种新型定子电阻在线识别算法 ;同时对低通滤波产生的磁通误差进行分析 ,介绍了一种磁通误差补偿方法 ,利用Powersys对此进行仿真 ,并给出仿真实验结果。
In order to improve the performance of direct torque control, the key techniques, the stator resistance identification and low-pass filter compensation, which effect the DTC’s performance and efficiency are mainly discussed in this paper. The stator resistance is derived from the motor’s dynamic model. The stator flux error producing by the low-pass filter is analyzed and compensated. The simulation result is presented.
