Reduced Order Observer Applied to a Linear Parameter Varying System with Unknown Input

This paper presents the design of a reduced order observer applied to a Linear Parameter Varying (LPV) system with unknown input. This procedure is employed to develop an actuator Fault Detection and Isolation (FDI) scheme. The observer's design and its stability conditions are guaranteed in terms of a Linear Matrix Inequalities (LMI). Two typical chemical industries processes examples are given to illustrate the use and performance of such approach.
