Abstract

We investigate the design of a higher-order PI observer for robustly detecting the faults in the linear timeinvariant system with disturbances. Based on the parametric solutions of Sylvester matrix equation, a necessary and sufficient condition for decoupling the disturbances from the residuals is proposed, and a parameterized method for designing the higher-order PI observers for robust fault-detection is established. The simulation of a numerical example validates the efficacy of the proposed parameterized design method for robust fault-detection.
