摘要:
研究一类由任意有限多个不确定子系统组成的切换系统的动态输出反馈鲁棒H∞控制问题.利用共同Lyapunov函数方法和凸组合技术,给出由矩阵不等式表示的控制器存在的充分条件,并设计了相应的子控制器和切换规则.采用消元法,将该矩阵不等式转化为一组线性矩阵不等式(LMIs).最后给出一个数值仿真实例证明结论的有效性.研究结果表明:通过切换,闭环系统在整个状态空间上的每个点都满足鲁棒H∞性能,而并不要求每个子系统在整个状态空间上都满足鲁棒H∞性能,甚至也不要求其渐进稳定.
Abstract:
Based on the common Lyapunov function approach and convex combination technique, the sufficient condition for the existence of sub-controllers is presented, which is in the form of matrix inequalities. Both sub-controllers and switching strategy are designed. Then, using the eliminated element method, the matrix inequalities are changed into linear matrix inequalities(LMIs). Finally, a simulation example is employed to illustrate the validity of the results. The results indicate that the closed loop system satisfies robust H∞ performance at each point in whole state-space through switching, although each sub-system does not satisfy the performance and even is not asymptotically stable.
