Delay-Dependent Reliable H Control for Linear Time-Varying Delay Systems via Adaptive Approach

This paper considers the problem of delay-dependent adaptive reliable H_infin controller design against actuator faults for linear time-varying delay systems. Based on the on-line estimation of eventual faults, the parameters of adaptive reliable H_infin controller are updating automatically to compensate the fault effects on system. A new delay- dependent reliable H_infin controller is established using linear matrix inequality (LMI) technique and adaptive method, which guarantees the stability and adaptive H_infin performance of closed-loop systems in normal and faulty cases. A numerical example and its simulations illustrate the effectiveness of the proposed method.
