Abstract
Abstract This paper describes the reconfiguration of a fuzzy controller based on a Fault Detection and Isolation system that uses input-output parity equations as a residual generator. The FDI system uses fuzzy logic in the residual evaluation and in the diagnosis step. An estimation of the size of the fault is made using the value of the residuals and their sensitivity respect the different faults. The result is the failure isolation, with the estimation of its possibility and its size. The accommodation is made using these results and information in the fuzzy rules of the controller. First the FDI system is described and then the method of accommodation is applied to a laboratory plant DC motor that presents sensor and actuator faults.
