Observer-based self-triggered FTC for Markovian jump networked systems

A resource -aware fault tolerant control (RA -FTC) issue is considered in this work for Markovian jump systems (MJS) via a self -triggered scheme. First, based on uncertain polytopic theory and system augmentation technique, a sliding mode observer is designed to reconstruct faults and states via the self -triggered nonuniform sampled outputs. Second, a self -triggered fault tolerant controller (ST -FTC) is constructed based upon the reconstructed fault and state signals. Then, the desired performance of the overall closed -loop system can be achieved. Third, with the aid of Lyapunov theorem and linear matrix inequality technique, the stochastically stabilization can be guaranteed under the action of the proposed ST -FTC. It is worthy noting that the self -triggered mechanism is firstly introduced for FTC of MJSs to reduce the computation resources. Finally, two examples are provided to show the effectiveness of the investigated RA -FTC scheme. (c) 2024 Elsevier Ltd. All rights reserved.
