报告题目：Stabilisation of hybrid stochastic systems in the presence of asynchronous switching and input delay

报告摘要： The talk concerns the pth moment and almost sure stabilization of a class of nonlinear hybrid stochastic system with input delays in both the switching signal and the state. By using Lyapunov functional approach, sufficient conditions are established in terms of sizes of the delays ensuring the pth moment exponential stability of the system. By developing a composite mode dependent Lyapunov function approach, we derive novel almost sure exponential stability criteria for a delay-free hybrid stochastic system without imposing the stability condition on the subsystems. The almost sure stability property of the hybrid system with delayed feedback controller is confirmed to be preserved as long as the corresponding delay-free system is almost sure exponential stabilization and the delays are small enough. Numerical examples are applied to demonstrate the theoretical results.
