摘　　要：近年来,被控系统的时变问题越来越引起控制领域的广泛关注,新的控制方法也随之不断被提出.首先,在分析时变系统分类方法的基础上,总结了研究时变系统的几个关键问题;随后给出了两种不同的时变系统模型描述方法,同时根据系统的时变特征,分析讨论了不同的时变系统控制方法,并总结出各自的研究现状及性能特点;最后,就时变系统研究趋势及核心问题探讨了时变系统控制问题的研究方向.In recent years, there is a hot problem on time-varying of the plant which becomes more and more increasingly concerned by control areas. Thus, a series of new control methods are proposed continuously. Firstly, the classification methods of the time-varying plants are analyzed and several key issues on such plants are summarized. Then two different methods on model description are proposed. Based on these, according to the differences on the time-varying characteristics, different control approaches are analyzed and the status and performance characteristics of time-varying system are surveyed. Finally, the perspective of time-varying control theory and associated research topics are briefly explored and discussed.
