Finite-time resilient sliding mode control of nonlinear UMV systems subject to DoS attacks

Abstract

The resilient sliding mode control (SMC) problem of unmanned marine vehicles (UMVs) under the framework of Finite-Time Stability (FTS) is studied in this work, where the network between the UMV and the remote console is supposed to suffer from DoS attacks. The nonlinear UMV is modeled by a T-S fuzzy model, and a novel sliding mode protocol is proposed. The FTS conditions for both the reaching phase and the sliding mode phase are given. It is shown that the FTS of the resulting closed-loop system can be established. A simulation example is finally presented to illustrate the effectiveness of the proposed control scheme.
