Distributed fault diagnosis observer for multi-agent system against actuator and sensor faults

نویسندگان

چکیده

Component failures can cause multi-agent system (MAS) performance degradation and even disasters, which provokes the demand of fault diagnosis method. A distributed sliding mode observer-based method for MAS is developed in presence actuator sensor faults. Firstly, faults are extended to state, transformed into a descriptor form. Then, mode-based unknown input observer proposed estimate state. Furthermore, adaptive laws introduced adjust parameters. Finally, effectiveness demonstrated with numerical simulations.

Distributed Adaptive Fault-Tolerant Consensus Control of Multi-Agent Systems with Actuator Faults

This paper presents an adaptive fault-tolerant control (FTC) scheme for leader-follower consensus control of uncertain mobile agents with actuator faults. A local FTC component is designed for each agent in the distributed system by using local measurements and certain information exchanged between neighboring agents. Each local FTC component consists of a fault detection module and a reconfigu...

Fault Detection and Diagnosis for A Multi-Actuator Pneumatic System

of the Dissertation Fault Detection and Diagnosis for A Multi-Actuator Pneumatic System by Kunbo Zhang Doctor of Philosophy in Mechanical Engineering Stony Brook University 2011 In pneumatic actuating systems, various kinds of faults are key factors in degrading system performance and increasing air consumption. It is therefore valuable to monitor pneumatic systems and implement predictive main...

A Fault Tolerant Flight Control System For Sensor And Actuator Faults

The purpose of the paper is to present an approach to detect, isolate and accommodate the sensor or actuator faults using bank of unknown input observers (UIO). Full order observers, reduced order observers, unknown input observers and Kalman Filter are widely used in state estimations [1]. After the estimation of states, fault detection and isolation can be provided by conducting residual anal...

Reconstruction of simultaneous actuator and sensor faults for the RECONFIGURE benchmark using a sliding mode observer ⋆

This paper considers the problem of reconstructing, simultaneously occurring actuator and sensor faults in a nonlinear system. The theory which will be developed in this paper is based on a sliding mode observer formulation, designed around an LPV model approximation of the nonlinear system. It extends previous work which has independently considered actuator and sensor faults reconstruction. H...

LMI-based sliding-mode observer design method for reconstruction of actuator and sensor faults

This paper presents a method to design Sliding Mode Observers (SMO) for a class of linear system using Linear Matrix Inequalities (LMIs). The switching surface is set to be the difference between the observer and system output. In terms of LMIs, a necessary and sufficient condition is derived for the existence of a sliding-mode observer guaranteeing a stable sliding motion on the switching surf...
