Robust and efficient predictive FTC: Application to wind turbines

The paper deals with the problem of robust predictive fault-tolerant control for non-linear discrete-time systems. The proposed approach starts with the fault estimation and then the fault is compensated with a robust controller. If the robust fault compensation does not provide satisfactory results, which means that the current state does not belong to the robust invariant set, then a suitable predictive control actions are 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. Subsequently, the proposed approach is extended to the linear parameter varying systems. The final part of the paper shows an illustrative example regarding wind turbines.
