摘 要: 研究一类不确定线性系统的混杂状态反馈保成本控制问题.系统矩阵和输入矩阵中含有时变不确定性.假设存在有限个备选的控制增益已知的控制器,并且任何单一的状态反馈控制器都不能镇定系统.基于单Lyapunov函数的方法,给出了混杂状态反馈保成本控制的充分条件及切换律的设计方案.当切换系统的控制增益未知时,利用多Lyapunov函数法,给出混杂状态反馈保成本控制的充分条件,并通过仿真验证了该方法的有效性. The hybrid state-feedback guaranteed control problem for a class of uncertain linear systems is discussed. Time-varying uncertainties are contained in both state matrix and input matrix. Based on single Lyapunov function method, sufficient conditions for hybrid state-feedback guaranteed cost control are given and the switching laws are constructed. When the controller gain matrices are unknown, a sufficient condition for hybrid state-feedback guaranteed cost control is also derived by means of multiple function technique. The simulation result shows the effectiveness of the proposed method.
