چکیده
The main objective of this paper is to present the MATLAB block-set that can be used for faulttolerant control of linear-parameter varying systems. In particular, the introductory part of the paper presents a theoretical background regarding the fault identification and control strategy. Subsequently, it is shown how to implement these theoretical results in Matlab/Simulink. The final part of the paper presents the experimental study regarding the twin-rotor system, which confirms the effectiveness of the developed tool.

Indirect Rotor Field-Oriented Control of Fault-Tolerant Drive System for Three-Phase Induction Motor with Rotor Resistance Estimation Using EKF
The performance of an Indirect Rotor Field-Oriented Control (IRFOC) scheme for Induction Motors (IMs) is strongly dependent on the motor parameters especially, rotor resistance. As such, to ensure high performance drive system, the variation of the rotor resistance due to the temperature increase need to be estimated based on the available terminal variables. However, the algorithm used to esti...

متن کاملA robust predictive actuator fault-tolerant control scheme for Takagi-Sugeno fuzzy 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 is based on a triple stage procedure, i.e. it starts from fault estimation while the fault is compensated with a robust controller. The robust controller is designed without taking into account the input constraints related...
