Finite-time stabilization for stochastic reaction-diffusion systems with Markovian switching via boundary control

This paper investigates the finite-time stability (FTS) for a class of stochastic Markovian reaction-diffusion systems (SMRDSs). First, a boundary control strategy is put forward. Un-der the designed boundary controller, a sufficient condition of FTS for SMRDSs is provided based on the method of Lyapunov-Krasovskii functional combined with inequality tech-niques.When there exists the incompleteness of transition rate information, we further study the problem of SMRDSs with partially unknown transition rates (TRs) by adding a set of symmetric free matrices. An FTS criterion is also obtained for this case. Theoretical results show that the case of completely known TRs is the special case of partially un-known TRs. Finally, simulation examples are presented to verify the validity of our derived results. (C) 2020 Elsevier Inc. All rights reserved.
