  1. 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.
