Boundary control of stochastic reaction‐diffusion systems with Markovian switching

Abstract

This article focuses on the boundary control of stochastic Markovian reaction-diffusion systems (SMRDSs). Both the cases of completely known and partially unknown transition probabilities are taken into account. By using the Lyapunov functional method, a sufficient condition is obtained under the designed boundary controllers to guarantee the asymptotic mean square stability for SMRDSs with completely known transition probabilities. For the case of partially unknown transition probabilities, we introduce free-connection weighting matrices to handle the boundary control problem. When external disturbance enters the system, a sufficient criterion of H-infinity boundary control is developed. Furthermore, robust stabilization is investigated for parametric uncertain SMRDSs in both cases. Two examples are presented to demonstrate the efficiency of the proposed approaches.

Impulsive effects on stabilization of stochastic nonlinear reaction-diffusion systems with time delays and boundary feedback control

“…Remark 3.3. The impulsive control approach was utilized to stabilize the RDSs [37][38][39]49] and the boundary control technique was also utilized to stabilize the RDSs [9,15,16,22,23,51,52]. To best of our knowledge, there are few works that investigate the FTS and stabilization of SNIRDSs with time delays and the boundary feedback control.…”

“…Boundary controllers, as a particular control technique for PDSs, can be efforts to achieve the required dynamic behaviors of such PDSs while saving cost and making it simple to implement [9,16,22]. The back stepping method has been used to explore boundary control for RDSs.…”

Boundary Control of Stochastic Korteweg-de Vries-Burgers Equations

“…Boundary control only needs to apply the actuators on the boundary of the spatial region, which has the characteristics of low cost and easy to realize. In recent years, boundary control has been studied by many scholars [1,5,8,9,12,13]. For the boundary control of deterministic systems, a classic method is the backstepping method.…”

Observer‐based H∞ control of a stochastic Korteweg–de Vries–Burgers equation

“…• It should be noticed that most of the works focus on stabilization of linear stochastic partial differential equations (PDEs) (see, e.g., References 21,22). However, many challenging problems for nonlinear stochastic PDEs have not been studied yet, which are still open.…”
