Robust guaranteed cost fault-tolerant control for uncertain networked control system with time delay and packet dropout

The problem of robust guaranteed cost fault-tolerant control is addressed for a class of uncertain networked control system with time delay and packet dropout. Based on Lyapunov time-delay-dependent stability theory, combined with the delay-departioning method and reciprocally convex combination technique, the sufficient conditions which ensure that the system is asymptotically stable are derived. The problem of guaranteed performance optimization is transformed into convex optimization problem with constraint conditions of linear matrix inequalities, and the parameter expressions of robust guaranteed controller are given. Theoretical analysis and simulation results both illustrate the feasibility of our approach.
