Reliable H∞ Control for Linear Systems against Either Sensor or Actuator Fault
نویسنده
چکیده
This paper studies the reliable dynamic output-feedback control of linear systems based on either component fault, that is, either sensor or actuator faults. A more practical continuous fault model of sensor and actuator than discrete model is considered. The resulting control systems are reliable in that they provide guaranteed asymptotic stability and H∞ performance when all control components is operational, as well as when either sensor or actuator faults occur. A given H∞ performance bound in failure cases is guaranteed and the H∞ performance in the nominal case is optimized. A numerical example is also given to illustrate the design procedures and their effectiveness. Key Words, Sensor fault, Actuator fault, Either fault, Reliable H∞ control, Linear matrix inequality

Reliable 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 ...

This paper deals with the issues of sensor fault detection for a class of Lipschitz uncertain nonlinear system. By definition coordinate transformation matrix for system states and output system, at first the original system divided into two subsystems. the first subsystem includes uncertainties but without any sensor faults and the second subsystem has sensor faults but is free of uncertaintie...
متن کاملRobust H∞ Fault –tolerant Control against Sensor and Actuator Failures for Uncertain Descriptor Systems
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 maintain...
متن کاملReliable Control System Design despite Byzantine Actuators
Sensor-actuator networks are increasingly being used in distributed control of large scale systems. Often these applications are mission-critical and are required to maintain satisfactory performance in the presence of component failures. On the one hand, sensor-actuator network components are becoming inexpensive but they also tend to be unreliable, especially when deployed in harsh or unpredi...
متن کاملArtificial Neural Networks, Adaptive and Classical Control for FTC of Linear Parameters Varying Systems
Three different schemes for Fault Tolerant Control (FTC) based on Adaptive Control in combination with Artificial Neural Networks (ANN), Robust Control and Linear Parameter Varying (LPV) systems are compared. These schemes include a Model Reference Adaptive Controller (MRAC), a MRAC with an ANN and a MRAC with an H∞ Loop Shaping Controller for 4 operating points of an LPV system (MRAC-4OP-LPV, ...
