Adaptive controller design for linear time-invariant systems with sensor failures

In this paper, the active fault-tolerant control design problem is addressed by using an adaptive method for linear time-invariant continuous-time systems with sensor failures. The considered loss sensor effective factors and bias faults of sensors are assumed to be unknown according to the practical case. For the sake of eliminating the effects of sensor faults, some adaptive schemes are developed to estimate the unknown eventual faults on-line and to construct the fault-tolerant controller based on the adaptive estimations. Then the asymptotic stability results are ensured by using the proposed static output feedback controllers via Lyapunov stability theory. The proposed design technique is finally evaluated in the light of a simulation example.
