Title
A robust fault-tolerant model predictive control for linear parameter-varying systems
Abstract
The paper deals with the problem of robust fault-tolerant model predictive control for non-linear discrete-time systems described by the Linear Parameter-Varying model. The proposed approach is based on a multi-stage stage procedure. Robust controller is designed without taking into account the input constraints related with the actuator saturation and deals with previously estimated faults. Thus, to check the compensation feasibility, employed robust invariant set takes into account the input constraints. If the current state does not belong to the robust invariant set, then a predictive control is performed in order to enhance the invariant set. This appealing phenomenon makes it possible to enlarge the domain of attraction, which makes the proposed approach an efficient solution for the fault-tolerant control. The final part of the paper shows an illustrative example for the variable-speed variable-pitch wind turbines.
