Fault-tolerant networked control systems

Abstract

With considering the possibility of sensors fault, this paper proposes a method for designing fault-tolerant controllers of networked control systems under consecutive packet dropout and time-varying delay. Based on the Lyapunov-Krasovskii theorem, sufficient conditions for guaranteeing robust stability of NCSs under all possible sensors failure, packet dropout, and time-delay are derived. Simulation results validate the presented results.
