Popis: | International audience; In this paper, a Fault Tolerant Control (FTC) design method based on Linear Parameter Varying (LPV) gainschedulingtheory is proposed. The main contribution is the design of a fault-tolerant state-feedbackobserver-based controller based on a polytopic LPV representation where faults are considered in thesame way that those parameters that vary with the operating point.Within this framework, the ranges offault magnitudes that are wanted to be tolerated can be specified as design parameters. Control specificationsare defined in terms of H∞ or H2 performance in combination with regional pole placement, as traditionallydone in conventional LPV control. Passive and active FTC formulations are developed, the latter assumingthe availability of on-line fault estimations. In both cases, the associated controller synthesis methods arebased on the well established LPV-LMI framework. Additionally, a fault estimation procedure is provided toallow the implementation of the active formulation. Finally, the use of the proposed method is illustrated byapplying it to the FTC of a two degree of freedom helicopter. |
