Actuator Fault-tolerant Control Design Based on Reconfigurable Reference Input

The prospective work reported in this paper explores a new approach in order to enhance the performance of an Active Fault Tolerant Control System. This proposed technique is based on a modified recovery/trajectory control system which considered a reconfigurable reference input when performance degradation occurs on system due to faults in actuators dynamics. The added value of this work is to reduce the energy spent to achieve desired closed-loop performance. The feasibility of this work is illustrated using a three-tank system for slowly varying reference inputs corrupted by actuators faults.
