Abstract :
Since failures of control components often occur in real world, this paper focused the problem of reliable control for a class of uncertain switched systems with time delay. By using Lyapunov function and linear matrix inequality approach, reliable controllers were designed to make the nominal systems be stable not only when all actuators were operational, but also when some admissible control components experienced failures under arbitrary switching signals. At the same time, the systems with all admissible uncertainties were still asymptotically stable. Finally, a simulation result shows the feasibility and validity of the designed method
