基于互联系统的鲁棒控制

Robust control based on interconnected systems

讨论了一类时滞互联系统的鲁棒控制问题。不同于以往的结论,所讨论系统中的不确定非线性互联项关于一具有未知增益的高阶多项式的函数有界,且不要求系统满足匹配条件。首先提出了能保证闭环系统渐近稳定的线性分散自适应控制器,然后给出了一类可使闭环系统最终一致有界稳定的分散非线性控制器。

This paper focuses on robust control problem for a.class of time-delay interconnected systems. Differing from former conclusions,the nonlinear uncertainties of the systems under study are bounded by high-order polynomial functions with unknown gains,and do not require the system satisfies matching aondition. First a class of linear decentralized adaptive controller is proposed which can guarantee the closed-loop system asymptotically stable. Then,a class of nonlinear decentralized state feedback controller is given to render the closed-loop system uniformly ultimately bounded stable.
