基于预测控制的双三相异步电机直接转矩控制策略

Direct Torque Control Strategy of Dual Three Phase Asynchronous Machine Based on Predictive Control

介绍了一种新颖的双三相异步电机直接转矩控制(DTC)策略。该策略根据预测控制算法来跟踪转矩和磁链的设定值,转矩和磁链的误差可在一个控制周期内得到补偿,从而有效降低转矩和磁链的脉动。通过系统仿真,验证了该控制策略是正确有效的。

A novel direct torque control （ DTC ） strategy of dual three-phase asynchronous machine was discussed. The strategy was able to track the setting value of torque and flux based on a predictive algorithm. The error of torque and flux could be offsetted in the control period, so the ripple of torque and flux was reduced effectually. Through system imitation, the validity of these strategies is proved.
