Paper Abstract

Based on Lyapunov equation and the generalized inverse theory, the design of fault-tolerant controller processing integrity to sensor for uncertain continuous-time system is proposed int his paper. The controller which all poles of the nominal closed-loop systems are placed within a prescribed circular region through state feedback is first addressed. Then based on a new Riccati-type equation, sufficient condition is derived for the existence of the fault-tolerant controller subjected to plant parameter perturbation and sensor failure. It is shown that the proposed design method preserve asymptotic stability in the presence of parameter perturbation, as well as in the case of sensor failure.
