Control mediante compensación de la saturación y de los filtros de detección de fallas

Abstract

Based on important results in the design of schemes of compensation for the control saturation problem and in the fault detection and diagnosis filter synthesis, in this paper a methodology for the implementation of the compensation schemes through the fault detection filters for the multivariable lineal systems is presented. The detection filter allows to obtain the saturation signal, which is necessary for the compensation in according to the adopted scheme. The methodology constitutes a technique for fault tolerant control due that the changes for effects of the control saturation are detected through the filter and at the same time allows the compensation immediately. This means that it is not necessary to specify previously the saturation levels.
