Nonlinear observer based sensor fault tolerant control for nonlinear systems
This paper deals with the problem of sensor fault tolerant control for Takagi-Sugeno nonlinear systems. Firstly, a residual generator is designed in order to detect and isolate sensor faults. Secondly, a nonlinear observer based controller, adopting the so-called parallel distributed compensation structure is designed. This controller is based on a weighted blending of the estimated states prov...
متن کاملDistributed Adaptive Fault-Tolerant Control of Uncertain Multi-Agent Systems
This paper presents an adaptive fault-tolerant control (FTC) scheme for a class of nonlinear uncertain multi-agent systems. A local FTC scheme is designed for each agent using local measurements and suitable information exchanged between neighboring agents. Each local FTC scheme consists of a fault diagnosis module and a reconfigurable controller module comprised of a baseline controller and tw...
متن کاملAdaptive Observer Based Fault Diagnosis for Satellite Attitude Control Systems
This paper presents a novel fault diagnosis method for satellite attitude control systems. Under Lipschitz condition on the nonlinear part of such systems, a nonlinear adaptive observer is for the actuator fault diagnosis. Moreover, the convergence and its speed of the developed algorithm are also investigated. Finally, simulation results have been included to demonstrate the feasibility and ef...
متن کاملAdaptive Fuzzy Backstepping Fault-tolerant Control for Uncertain Nonlinear Systems Based on Dynamic Surface
An adaptive fuzzy fault-tolerant control design scheme for a class of perturbed and strict feedback nonlinear systems with actuators faults is proposed. The fuzzy logic systems are used to approximate to the nonlinear functions and the fault functions of systems. The continuous robust term is adopted to minimize the influence of modeling error or disturbance. Meanwhile, the dynamic surface cont...
متن کاملVoting Algorithm Based on Adaptive Neuro Fuzzy Inference System for Fault Tolerant Systems
some applications are critical and must designed Fault Tolerant System. Usually Voting Algorithm is one of the principle elements of a Fault Tolerant System. Two kinds of voting algorithm are used in most applications, they are majority voting algorithm and weighted average algorithm these algorithms have some problems. Majority confronts with the problem of threshold limits and voter of weight...
