摘要
This paper studies the problem of robust H∞ output feedback controller via state-reset for linear uncertain discrete-time switched systems. Using multiple Lyapunov functions, we address an output feedback controller under arbitrary switching signals, in which an H∞ performance is required. The condition is shown in the form of linear matrix inequalities (LMI). Finally, a numerical example shows the feasibility of the designed controller and illustrates that the new sufficient condition has lower conservation and more optimized H∞ performance.
