| 摘 要： | 开关磁阻电机固有的高度非线性特性使传统的平均转矩控制方法难以消除转矩脉动,也限制了它在高性能伺服系统中的应用。文中采用新型的直接瞬时转矩的控制策略,将瞬时转矩作为控制对象,在滞环控制的基础上通过PWM调制,结合在换相区间的转矩矢量分配函数,使瞬时转矩精确地跟随参考转矩。控制策略应用于一台样机控制系统,实验结果验证了控制策略的有效性。

| Abstract: | The inherent nonlinearity of the switched reluctance motor (SRM) makes it impossible to eliminate torque ripple for conventional average torque control method, which also restricts its application in high performance servo. The direct instantaneous torque control strategy was adopted. In order to track the reference torque accurately, the instantaneous torque was directly controlled by hysteresis and PWM control with torque sharing function during the phase commutation. The control strategy was applied to a prototype motor control. Finally, the experiment verified the effectiveness of the strategy. |
