Zonotopic Fault Estimation Filter Design for Discrete-time Descriptor Systems ?

This paper considers actuator-fault estimation for discrete-time descriptor systems with unknown but bounded system disturbance and measurement noise. A zonotopic fault estimation filter is designed based on the analysis of fault detectability indexes. To ensure estimation accuracy, the filter gain in the zonotopic fault estimation filter is optimized through the zonotope minimization. The desi...

Robust Fault Detection with Unknown-Input Interval Observers Using Zonotopes

This paper presents the problem of robust fault detection using unknown-input interval observers. These observers face the robustness problem using two complementary strategies. First, disturbances considered as unknown inputs are decoupled. Second, process/measurement noise and modeling uncertainty are considered unknown but bounded by intervals. Their effect is addressed using an interval sta...

LMI-based strategies for designing observers and unknown input observers for non-linear discrete-time systems

The paper deals with the problems of designing observers and unknown input observers for discrete-time Lipschitz non-linear systems. In particular, with the use of the Lyapunov method, three different convergence criteria of the observer are developed. Based on the achieved results, three different design procedures are proposed. Then, it is shown how to extend the proposed approach to the syst...

Fault Detection for Linear Switched Systems with Average Dwell Time Using Unknown Input Observers

The linear switched system is a kind of hybrid system that simultaneously possesses characteristics of both continuous event systems and discrete event systems. In this paper the issue of fault detection of switched systems is investigated using unknown input observers (UIO) and an average dwell time approach. The key parameter of UIOs is designed by solving linear matrix inequalities, which di...

An Unknown Input Observer for Fault Detection Based on Sliding Mode Observer in Electrical Steering Assist Systems

Steering assist system controls the force transfer behavior of the steering system and improves the steering probability of the vehicle. Moreover, it is an interface between the diver and vehicle. Fault detection in electrical assisted steering systems is a challenging problem due to frequently use of these systems. This paper addresses the fault detection and reconstruction in automotive elect...
