Decentralized dynamic output feedback reliable controller design for GCS of large-scale systems with delays in interconnections

For a class of large-scale systems with time delays in subsystem interconnection, reliable guaranteed cost stabilization (GCS) with continual gain actuator faults is presented. Based on the lyapunov method and linear matrix inequality (LMI), a sufficient condition for the existence of decentralized dynamic output feedback reliable controller is given. The design guarantees the system asymptotic stability. Simulation results show the effectiveness of the design method.
