| 摘 要： | 提出了一个基于开关磁阻电机电感模型的滑动模型观测器来估计电机的位置和速度。仿真结果显示当电机的转速高于 2 0r/min时 ,此观测器能得到高分辨率的转子位置估计结果。为了在整个调速范围实现无传感器控制 ,还分别研究了另两种在接近零转速和起动阶段使用的控制方法来判断开关时刻。在全部调速范围内对整个系统进行了仿真和实验 ,结果令人满意。

| Abstract: | A sliding mode observer is developed to estimate the rotor position and speed of switched reluctance motors(SRM) based on inductance model of SRM in this paper. Simulation results show that the proposed observer will estimated the rotor position with high resolution when the rotor speed is above 20r/min. To realize senseorless control at all speed range, other two algorithm is proposed to detect turn-on/turn-off instant at near zero speeds and starting moment. Simulink simulation shows that satisfactory results can be obtained at a full speed range. |
