Robust H∞ Fault –tolerant Control against Sensor and Actuator Failures for Uncertain Descriptor Systems

چکیده
Robust ∞ H fault-tolerant control against actuator and sensor failures for a class of uncertain descriptor systems via dynamical compensators is investigated. Based on ∞ H theory in descriptor systems, a method of designing dynamical compensators is presented. The dynamical compensator guarantees that the resultant closed-loop system is regular, impulse-free and stable, furthermore, it maintains certain ∞ H norm performance in the normal condition as well as in the event of simultaneous failures of sensor and actuator and parameter uncertainties. A numerical example shows the effect of the proposed method.

متن کاملRobust Control of A Class of Nonlinear Uncertain Systems Fault Tolerance Against Sensor Failures and Subsequent Self Recovery
In this paper, the problem of devising a fault-tolerant robust control for a class of nonlinear uncertain systems is investigated. Possible failures of the sensors measuring the state variables are considered, and robust measures are developed to identify the stability-vulnerable failures. Based on evaluation of the robust measures, a fault-tolerant robust control will switch itself among sever...
متن کاملThe Study for Guaranteed Cost Fault Tolerant Control of the Networked Control Systems
In this paper, the problem of guaranteed cost fault-tolerant control for networked control systems (NCSs) is discussed based on Lyapunov stability theory and Linear Matrix Inequality (LMI). The sufficient conditions possessing robust integrity against actuator failures are given by adopting memory state feedback control law, which can meet a cost function for closed-loop networked control syste...
متن کاملReliable H∞ control of discrete-time systems against random intermittent faults
A passive fault-tolerant control strategy is proposed for systems subject to a novel kind of intermittent fault, which is described by a Bernoulli distributed random variable. Three cases of fault location are considered, namely, sensor fault, actuator fault, and both sensor and actuator faults. The dynamic feedback controllers are designed not only to stabilise the fault-free system, but also ...
