摘要
研究了一种基于有限元分析的开关磁阻电机的位置估算方法。该方法首先利用有限元分析得到SRM无位置算法所需参数,建立SRM的非线性电感模型,通过滑模观测器得到SRM的转子位置和速度,最后在ANSOFT场路耦合仿真平台上对该方法进行验证,仿真结果验证了该无位置算法具有较好的精确度。
The novel position estimation method of the switched reluctance motor using finite element analysis was suggested.The required parameters were received by the finite element analysis of SRM,the non-linear inductance model was established,and the rotor position and speed was calculated by the sliding mode observer.The method was verified on ANSOFT field-circuit coupled simulation platform.The co-simulation results show that the approach has fine performance in position estimation.
