一种无位置传感器的SRM控制策略研究

A SRM Control Strategy Without Position Sensor

开关磁阻电机(SRM)有结构简单、效率高、鲁棒性好等优点,应用范围愈加广泛,但位置传感器的引入增加了结构的复杂性,降低了效率和鲁棒性,提高了系统成本,为了解决这个问题,论文研究了一种无位置传感器的控制策略——改进型简化磁链法控制。论文详细阐述了改进型简化磁链法的基本原理和实现方法,并对基于这种控制策略的开关磁阻电机的控制进行了Matlab仿真。仿真结果表明该种控制策略可以实现无位置传感器的开关磁阻电机的转速的调控。

Switched reluctance motor（SRM）has the advantages of simple structure,high efficiency and good robustness,it is applied more widely,but the introduction of the position sensor and increases the complexity of the structure,reduce the efficiency and robustness,and raise the cost of the system,in order to solve this problem,a kind of sensorless control strategy—the modified method of simplified flux control is studied in this article.The basic principle and implementation method of modified simplified flux method are introduced in detail,and based on this kind of control strategy of the switched reluctance motor control is simulated by Matlab.The simulation results show that this control strategy can achieve sensorless switched reluctance motor speed control.
