Abstract
This paper proposes a fault-tolerant control (FTC) scheme for polytopic linear parameter varying (LPV) systems. We first propose a fault compensator whose structure is simple, but effective against actuator faults. Then, in order to show its basic idea, we consider a state feedback FTC scheme based on the fault compensator. Next, the FTC algorithm is extended to output feedback FTC scheme. The FTC scheme for LPV systems involves a fault compensator based on the estimated fault and a robust observer based on linear matrix inequality (LMI). The proposed FTC method is applicable for a variety of systems and guarantees the robust stability of the system in the event of actuator faults. Numerical examples are given to demonstrate its effectiveness.
