摘要
开关磁阻电机具有结构简单、调速范围宽、性价比高等优点,但其转矩脉动较大导致了振动和噪声比其他调速系统严重,制约了它在一些场合中的应用。本文将直接转矩控制技术应用到开关磁阻电机中,对电机转矩进行控制,仿真结果证明,此技术能够将磁链矢量幅值很好的控制在滞环带内,从而有效地控制转矩脉动,降低电机的振动和噪声。
The switched reluctance drive system has simple structure, wide speed variation range, high cost performance and some other special property, and its greater torque ripple also results in more serious vibration and noise than other speed regulating ＇systems, which restricts its application in some field. The direct torque control technology is used in switched reluctance drive system to control the torque of the motor. The simulation results prove that the technology does well in controlling the flux vector amplitude in hysteresis band and effectively controls the motors torque ripple to inhibit its vibration and noise.
