Reliability importance measures for fault tolerant control allocation

This paper proposes a reliable control allocation scheme for fault tolerant control to guarantee the dependability of the system. The reliability of the actuators is used by the control allocation scheme to redistribute the control signals to the remaining actuators when a fault or failure occurs. The paper provides a presentation of the reliability importance measures and degradation model used to represent the reliability. The control allocation scheme shows that actuators faults and/or failures can be handled easily. A benefit of incorporate the reliability indicators on the over-actuated control system design is to improve the safety of the system.
