报告内容：This talk is concerned with the stabilisation of nonlinear hybrid stochastic  differential  equations (SDEs). Different from the classical continuous-time feedback control, we here use the feedback control based on discrete-time state observations.

This stabilisation problem has been intensively studied by many researchers since 2013.  The common restrictive condition imposed in the existing papers is that both drift and diffusion coefficients of the underlying hybrid SDE need to satisfy the linear growth condition (namely bounded by linear functions). It is this restrictive condition that excludes many SDE models in the real world. It is therefore necessary and important to establish a new theory which shows how to design the feedback controls based on the discrete-time state observations in order to stabilise highly nonlinear hybrid SDEs.  In this talk, we will show such feedback controls under the condition that both drift and diffusion coefficients of the underlying hybrid SDE may grow at most polynomially.
