【摘要】 For a class of switched linear systems, we propose a dwell time strategy depending on the state of systems. This switching strategy not only makes the asynchronous H∞state-feedback switched systems stable but also shortens the active time. A new result on stability and l2-gain analysis for switched systems is given where the Lyapunov functions are allowed to be increasing during the running time of subsystems, at the same time, the Lyapunov functions do not contain the limit of μ. By using the dwell time strategy depending on the state of systems, sufficient conditions for the desired H∞controller of switched linear systems are derived.Then the result is expanded to nonlinear switched systems. A numerical example is provided to demonstrate the effectiveness of the proposed design approach.更多还原
