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