摘　　要：介绍了一种基于PWM电流微分的同步磁阻电机转子位置角检测方法。逆变器采用三相三角载波PWM调制方法,通过对载波频率电流微分表达式进行推导,进行转子位置的估算,并构建无位置传感控制系统。利用MATLAB/Simulink进行仿真,仿真结果表明,所设计的位置估计系统能够准确地估计出电机转子位置。A method of rotor position angle detection for synchronous reluctance motor based on PWM current differen-tiation was introduced.Three-phase triangular carrier PWM modulation was adopted in the inverter.The rotor position was estimated by calculating of differential expressions for carrier frequency currents.Simulation was carried out under MAT-LAB/Simulink,the simulation results show that the designed position estimation system can accurately estimate the rotor position of the motor.
