Actuator Fault Detection and Accommodation in Distributed Parameter Systems
Abstract: This paper presents a general framework for model-based fault detection and accommodation for a class of distributed parameter systems with control actuator faults. A set of dedicated observers, each with its own time-varying threshold is constructed to detect the occurrence of fault in the corresponding actuator and reduce fault detection time. Additionally, an adaptive diagnostic ob...
متن کاملComments on actuator fault accommodation
The present work concerns the problem of progressive accommodation to actuator failure. An optimal nonlinear controller synthesis approach is formulated on the basis of the closed loop stability objective. The authors show the interest of the proposed method even for a local analysis when a linear approximation is used. This work focuses on a solution to ensure stability while accommodating to ...
متن کاملApplied Actuator Fault Accommodation in Flight Control Systems Using Fault Reconstruction Based FDD and SMC Reconfiguration
Historically, actuators’ redundancy was used to deal with faults occurring suddenly in flight systems. This technique was generally expensive, time consuming and involves increased weight and space in the system. Therefore, nowadays, the on-line fault diagnosis of actuators and accommodation plays a major role in the design of avionic systems. These approaches, known as Fault Tolerant Flight Co...
متن کاملNonlinear Approach of Actuator Fault Accommodation
In this paper, a method of actuator fault accommodation for a class of nonlinear systems is proposed. It concerns the problem of progressive accommodation to actuator failure. This strategy is based on t he optimal nonlinear controller, and its objective to maintain the system closed loop stability. The authors show the interest of the proposed method even for a local analysis when a linear app...
متن کاملFault Accommodation for near Space Hypersonic Vehicle with Actuator Fault
Based on fuzzy control and sliding mode observer technique, a fault accommodation strategy is proposed for near space hypersonic vehicle (NSHV) with actuator fault in this study. Firstly, the Takagi-Sugeno (T-S) fuzzy model is implemented to represent the NSHV nonlinear dynamics, and a bank of sliding mode observers are designed for the established T-S model, which are used to generate the resi...
