FAULT DIAGNOSIS IN LINEAR PARAMETER VARYING SYSTEMS

This paper presents a new approach to solve the FDI (Fault Detection and Isolation) problems in Linear Parameter-Varying (LPV) systems. A sufficient condition is established for guaranteeing fault sensitivity performance. The design problem is formulated within the LPV polytopic modeling framework and solved using LMI optimization techniques. The overall method is applied to a secondary circuit of a Nuclear Power Plant (NPP). Experimental results show the efficiency of the proposed method.
