Robust Fault-Tolerant Control for Descriptor Systems

Robust 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...

Predictive and robust fault-tolerant control for Takagi-Sugeno systems

The paper deals with the problem of robust predictive fault-tolerant control for nonlinear discrete-time systems described by the Takagi-Sugeno models. The proposed approach consists of three steps, i.e. it starts from fault estimation, the fault is compensated with a robust controller, and finally, when the compensation is not successful then a suitable predictive action is performed. This app...

Robust Takagi-Sugeno sensor fault tolerant control strategy for nonlinear system

Fault Tolerant Control for Induction Motor Drive Using Descriptor Approach

This paper presents an active fault tolerant control (FTC) strategy for induction motor drive that ensures trajectory tracking and offset the effect of the sensor faults despite the presence of load torque disturbance. The proposed approaches use a fuzzy descriptor observer to estimate simultaneously the system state and the sensor fault. The physical model of induction motor is approximated by...
