交流传动系统新型控制策略研究

A Survey of Research on Novel Control Strategies for AC Drive System

交流电机是非线性、多变量、强耦合的被控对象,在一些对控制性能要求较高的场合,传统的控制策略难以对其达到有效的控制。本文综述了预测控制、内模控制、自适应控制、鲁棒控制、智能控制以及滑模控制等交流传动系统中出现的一些新型控制策略,详细分析了它们各自的特点和应用情况。最后,对交流传动控制策略的发展前景提出了自己的观点。

AC is a controlled object of nonlinear, multivariable and complicated coupling. Under some special condition, it is difficult to be controlled effectively by conventional control method. Some kinds of novel control strategies for AC drives, which include model predictive control, internal mode control, adaptive control, robust control, intelligent control, sliding-mode control etc, are summarized in this paper. Their features and application on AC are analyzed explicitly. Finally, the prospects of control strategies for AC drivers are presented.
