摘　　要：提出一种将有限状态模型预测控制运用于无位置传感器的无刷直流电动机方法。在实现过程中无需计算功率管的占空比和换相时间,而是采用几个状态之间的比较切换实现开通相和关断相电流的变化速率的匹配,从而抑制换相转矩脉动,仿真和实验结果验证了该方法的有效性。A novel method based on finite state model predictive control to suppress commutation torque ripple for brushless DC motor was presented. Without calculating the duty cycle and commutation time,the change rates of the on-phase current and the off-phase current were matched by switching among the several commutation states to suppress commutation torque ripple. Simulation and experiment results show the effectiveness of this method.
