Robust D-stable fault tolerant control for delta operator formulated uncertain systems with state delays

This paper is concerned with the problem of fault tolerant control for delta operator time-delay uncertain systems with regional pole constraints. Sufficient conditions of robust D-stability for delta operator formulated fault tolerant control systems with state delay are presented in terms of Lyapunov-Krasovskii stability theory and Linear Matrix Inequality (LMI) approach. When this LMI is feasible, the parameterized representation of the desired state feedback controller is also obtained. A numerical simulation shows the effectiveness of the proposed method.
