Summary

This paper presents a general framework for analyzing stability of linear impulsive stochastic systems (LISSs). Some simple mean square stability criteria for the three types of LISSs are firstly derived by analyzing an equivalent system. By exploring the hybrid characteristics of impulsive systems, the novel quasi-periodic composite polynomial Lyapunov function and the time-varying discretized Lyapunov function are developed, which leads to unified dwell-time–based criteria for mean square stability and almost sure stability of LISSs without imposing the stability condition on continuous- and discrete-time dynamics. Next, based on the established stability criteria, the synthesis problem of state-feedback controller is solved. The computational complexity and the comparison with existing results on the deterministic systems are discussed. Finally, numerical examples are provided to illustrate the usefulness of the proposed results.
