非线性系统自适应控制及其在电力系统中的应用

电力系统中存在众多不确定的参数，所面临的运行条件和外界扰动复杂多变，有必要引入自适应控制理论来处理这些不确定因素。非线性系统的自适应控制与线性系统相比，在研究方法等方面都有着很大的不同，目前处在继续发展的阶段。文章首先对近十几年来非线性系统的参数自适应控制、鲁棒自适应以及智能化自适应控制做了简明的归纳，然后介绍了其中一些研究成果在电力系统稳定与控制研究中的应用，最后对全文做了总结和展望。

A Survey on Adaptive Control of Nonlinear Systems and Its Application in Power Systems

There are many uncertain parameters in power system that faces with complex and various operating modes and external disturbances, thus it is necessary to deal with these uncertain factors by adaptive control theory. The research approach for adaptive control of nonlinear system is obviously different to that for linear system and is still being developed. In this paper firstly the authors make a concise survey on parametric adaptive control, robust adaptive control and intelligent adaptive control of nonlinear systems; then the applications of these research findings in the research on power system stability control; finally, the summary of this paper and the prospects of the development of adaptive control theory are given.
