报告摘要：

This talk concerns with stochasticstabilization and destabilization of nonlinear and time-varying hybrid systems.In this talk, a suitable functionis designed such that the corresponding Wienernoise perturbationeither stabilizes or destabilizes a given nonlinear andtime-varying hybrid systemwith a Markov jump parameter. The correspondingperturbed system is a nonlinear and time-varying hybrid Itô stochasticdifferential system. To this end, the basic properties, including the existenceand uniqueness of the local and global solutions and the non-zero property ofsolutions of the nonlinear and time-varying hybrid stochastic systems, arefirstly investigated as the theoretical basis of the paper. Secondly, twotheorems and the corresponding corollaries on the stability and instability ofthe hybrid stochastic systems are established. Thirdly, the design method forfunctionis then proposed based on the established theorems. Finally, weillustrate our method using two examples.
