摘要
In this paper, a new approach to design a Fault-Tolerant Control (FTC) based on Linear Parameter Varying (LPV) Admissible Model Matching (AMM) is proposed. The suggested strategy is an active technique that requires the fault to be detected and estimated by the FDI scheme. Then, the controller is redesigned accordingly. In this work, faults are expressed as a change in the system dynamics (in particular, in the model parameters). The main contribution of the proposed approach is to consider the fault as a scheduling variable in the LPV model that allows the controller reconfiguration. The range of the scheduling variables (fault magnitude and system operating point) allow to specify the set of admissible behaviors. The effectiveness and performances of the method have been illustrated in a two degree of freedom helicopter.
