The solution of the Linear Quadratic problem under actuator faults is investigated. Both fault accommodation and system recon…guration procedures need the controller to be re-designed, which means solving the Algebraic Riccati Equation (ARE) associated with the faulty system model. A progressive accommodation strategy, based on the NewtonRaphson scheme for solving the ARE is proposed, and it is shown that it signi…cantly reduces the risk associated with system instability and/or control inadmissibility which result from fault detection and isolation delay, and computation time of the accommodated control.

“…Fault tolerant control is emerging as an important topic of research [1], [2], [3], [4], [5]. As automated systems become more complex, a key challenge is how to achieve (at worst) graceful degradation in performance in the event of a fault associated with an actuator, sensor or component subsystem.…”

Previous work has considered the use of sliding mode observers for fault detection and isolation (FDI) in uncertain linear systems whereby the unknown faults are reconstructed by appropriate processing of the so-called equivalent output error injection. The paper builds on this work and considers such a scheme within the broader context of fault tolerant control. Specifically, by correcting the faulty measurement by an estimate of the fault obtained from the sliding mode FDI scheme, good closed-loop performance is still maintained. An example of such a scheme, which has been implemented on a laboratory dc motor rig, is described.

“…There is an increasing demand for those systems to be safer and more reliable, thus leading to take into account, at their very early design stage, fault detection and isolation (FDI) and fault tolerant control (FTC) issues (Staroswiecki and Gehin 2001).…”

This paper deals with the design of H 1 fault detection filters for discrete-time systems with multiple time delays, in which total decoupling of the fault effects from unknown inputs, including model uncertainties and external plant disturbances, is impossible. Through the appropriate choice of the filter gain, the filter is convergent if there is no fault in the system, and the effect of disturbances on the residual is minimized in the sense of H 1 norm. The problem of achieving satisfactory sensitivity of the residual to faults is formulated and its solution given. The detection threshold associated with the filter is also discussed. Finally, a wind tunnel example illustrates the efficiency of the proposed method.
