Actuator Fault Tolerant Control System with Re-configuring Reference Input Design based on MPC
Résumé
This paper deals with Active Fault Tolerant Control System based on a reconfigurable reference input when performance degradation occurs on system due to faults. The main idea/contribution is to consider the reconfigured system as an open loop controlled by a classical MPC strategy in order to design “one-line” new reference inputs. The added value of this method is to reduce the energy spent to achieve desired closed-loop performance and consequently to maintain a reliable system in dynamical way. The effectiveness of the proposed approach is illustrated using a three-tank system corrupted by abrupt actuator faults.
