Abstract: The problems of delay-dependent robustly exponential stability and stabilisation of a class of special neutral systems with interval time-varying delays, and subject to actuator failures, are investigated in this paper. For the special switched system resulting from actuator failures, a class of switching laws incorporating the average dwell time method is proposed. Based on the switching strategy of average dwell time method, delay-dependent sufficient conditions for exponential stability and stabilisation of the special switched systems are established in terms of linear matrix inequalities by choosing appropriate piecewise Lyapunov-Krasovskii functional. Also, the synthesis of stabilising hybrid state-feedback controllers is done such that the closed-loop system is robustly exponentially stable. The effectiveness of the proposed robust control scheme is demonstrated by simulation example. Copyright ? 2010 Inderscience Enterprises Ltd.
