摘要
开关磁阻电机的主要缺点是转矩脉动较大以及振动和噪声比其他调速系统严重。这里将直接转矩控制技术应用到开关磁阻电机中,以转矩脉动最小化为主要控制目标,在此基础上建立了直接转矩控制的仿真模型。仿真及实验研究表明,直接转矩控制技术能够将磁链矢量幅值很好地控制在滞环带内,从而有效地控制转矩脉动,降低电机的振动和噪声。
The switched reluctance motor has disadvantages such as greater torque ripple,more serious noise and vibration problems than other drive systems.The direct torque control technology is used in the switched reluctance drive systems,which takes the torque ripple minimization as control goal.The simulation model of direct torque control of switched reluctance motor is built based on the theory.The results show that the amplitude of the flux can be well controlled in hysteresis band,the motor＇s torque ripple and noise problems are effectively inhibited.
