Abstract: In order to avoid the rigorous conditions of reconfiguring system states directly, controller reconfiguration design schemes of dynamic stabilization and set-point tracking were put forward when linear time invariant systems had actuator faults. Based on the reconfiguration module (RM) notion and fault-masking approach, the extended virtual actuator was derived, attaining a unified representation of static and dynamic reconfigured modules. The RM and nominal controller together formed the reconfigurable controller. The reconfiguration goals including closed-loop stability and tracking performance were both achieved. Simulation results showed that closed-loop stability can be insured in the presence of actuator faults and tracking reconfiguration goal is also restored.
