摘要
提出一种新型的交互式MRAS。在基于无功功率的MRAS基础上,将参考模型和可调模型互换,同时辨识感应电机转速和定子漏感。该方法引入无功功率物理量,使参考模型中不包含纯积分和定子电阻,并且通过辨识并在线调整定子漏感,消除了定子漏感变化对MRAS速度辨识精度的影响。仿真结果表明,该方法提高了系统对参数变化的鲁棒性,拓宽了调速范围,且具有结构简单的特点。
A novel mutual MRAS was presented. It estimated speed and stator leakage at the same time by using change the reference model and adjustable model. Pure integration and stator resistance were removed from the reference model by using reactive power. To eliminate the influence of stator leakage change,the identification and compensation of stator leakage on - line was proposed in this method. The simulation result demonstrated that this method improved the robust and extended speed identification range, and had the advantage of simplicity construct.
