In this paper we propose a new approach of fault estimation and Fault Tolerant Control (FTC) applied to Linear Time Delay (LTD) systems. To estimate the sensor faults we use the descriptor approach. This method consists in augmenting the state system by considering the faults as an auxiliary state. The used observer can estimate simultaneously both the(More)
The additive fault tolerant control (FTC) for delayed system is studied in this work. To design the additive control, two steps are necessary; the first one is the estimation of the sensor fault amplitude using a Luenberger observer with delay, and the second one consists to generate the additive fault tolerant control law and to add it to the nominal(More)
This work presents an approach for fault diagnosis of discrete time singularly perturbed systems (SPS) with time-delay, called parity space in order to generate fault detection residual. In fact, to decompose the full system into slow and fast subsystems, we based on singular perturbation method. Then, we can use the reduced residual generated basing on(More)
