  1. ; ; (, Proceedings of 2022 American Control Conference, Atlanta, Georgia, USA, June 8-10, 2022.)
    A set-theoretic Failure Model and Effect Management (FMEM) strategy for stuck/jammed actuators in systems with redundant actuators is considered. This strategy uses a reference governor for command tracking while satisfying state and control constraints and, once the failure mode is known, generates a recovery command sequence during mode transitions triggered by actuator failures. In the paper, this FMEM strategy is enhanced with a scheme to detect and isolate failures within a finite time, and to handle unmeasured set-bounded disturbance inputs. A numerical example is reported to illustrate the offline design process and the online operation with the proposed approach.

    This paper proposes a Failure Mode and Effect Management (FMEM) strategy for constrained systems with redundant actuators based on the combined use of constraint admissible and recoverable sets. Several approaches to ensure reconfiguration of the system without constraint violation in the event of actuator failures are presented. Numerical simulation results are reported.
