Stochastic Discrete-Time Delay Feedback Stabilization for Nonlinear Systems Under the Sublinear Expectation Framework
Abstract
This paper is concerned with the stochastic stabilization problem for nonlinear systems by $G$ -Brownian motion with feedback control based on discrete-time state observations with a time delay. By constructing an auxiliary system, which is a continuous-time stochastic system driven by $G$ -Brownian motion, we establish a sufficient criterion in terms of the observation gap $\tau $ and the time delay $\tau _{0}$ to ensure the quasi-surely exponential stability of the stochastic controlled system. Moreover, implementation of the control strategy is provided. Finally, an example is given to demonstrate the theoretical result.
