摘要针对一种半对称式双三相异步电机,提出两种电流预测控制算法。一种为基本算法,另一种为在基本算法的基础上通过引入合理近似而实现的模块化算法。相对而言,后者更为简洁,且易于在其他一些结构更为复杂的多相电机中进行推广。此外,针对离散控制的延时对上述两种算法带来的稳定性问题进行分析,并给出改进方案。实验结果表明,两种电流预测控制算法均能实现良好的电流控制效果,同时该文针对稳定性问题的改进方法也是有效的。

Abstract：For an asymmetrical dual three phase induction machine,two predictive current control methods are proposed.One of them is the basic method.Based on this,the other modularized method is suggested with reasonable assumption.Comparing to the basic method,the latter is more concise and easy to be applied to some other more sophisticated multi-phase machines.Besides,the stability issue of these two predictive current control strategies caused by the delay of the discrete control is analyzed,and one improvement solution is provided.Experimental results show that the two proposed predictive current control strategies can achieve a good current performance.Meanwhile,the effectiveness of the improvement on the stability issue is also validated.

Key words： Dual three phase induction machine predictive current control modularized stability
