摘　　要：开关磁阻电机具有十分复杂的动态模型，本文在一定的条件下，建立了开关磁阻电机的状态方程，给出了状态观测器的基本形式。并利用在线电流的检测来预估拍电感L（θ），简化状态观测器的模型。根据观测器收敛条件确定状态观测器增益矩阵。并通过实验，证明了该方法的正确性。Dynamic model of a switched reluctance motor is rather complicated. In this paper, equations of condition of the switched reluctance motor are established and the basic form of the condition monitor is provided under given conditions. Besides, the phase inductance L(θ) is estimated by checking on the on-line electric current. Thus the modelling of condiition monitor can be simplified. The gain matrix of the condition monitor is determined according to the conditions of convergence of the monitor. The correctness of the method is finally verified through experiments.
