摘要
自抗扰控制器(ADRC)在感应电机控制中取得了优良的控制效果,但控制器参数整定比较困难.本文从时间尺度的概念入手分析ADRC参数整定问题,通过理论分析得出感应电机的时间尺度,并结合时间尺度与ADRC参数的关系进行参数整定,得到了感应电机按定子磁场定向矢量控制的ADRC控制器参数整定方法,该方法尤其适于多台电机的参数整定.仿真结果表明该方法可行,为感应电机ADRC提供了一种参数整定方法.
Active disturbance-rejection controller (ADRC) has been successfully used in induction motor (IM) control system. But ADRC parameters are difficult to be tuned. To research ADRC parameters tuning, the time scale of IM is deduced by theoretic analysis. Combining the relations between scale time and ADRC parameters, we proposed a new ADRC parameter-tuning method for IM control system, which is based on the oriented vector control of stator flux. Finally, a digital simulation study is carded out and simulation results show the proposed method makes ADRC parameter tuning easier and more effective in IM control system, especially for series motors parameters tuning.
