直接转矩控制在开关磁阻电机中的应用

开关磁阻电机有角度位置控制、电流斩波控制和PWM控制等传统控制方式,但上述控制方式下系统转矩脉动较大,导致振动和噪声比其他调速系统严重,制约了它在某些场合中的应用.文章将直接转矩控制技术应用到开关磁阻电机中,建立了直接转矩控制的仿真模型.仿真研究表明直接转矩控制技术能够将磁链矢量幅值很好的控制在滞环带内,从而有效地控制...

Application of Direct Torque Control Technology into Switched Reluctance Motor

Such traditional control methods as angle position,current chopping and pulse width modulation control were applied to the switched reluctance drive system.However,the systems with these control modes had the greater torque ripple and noise problems which were more serious than those of other drive systems,restricting its application in some fields.The application of direct torque control technology into the switched reluctance drive system was introduced and the simulation model to control the torque was built.The results showed that the amplitude of the flux was well controlled in hysteresis band,the motor’s torque ripple and noise problems was effectively inhibited.
