Abstract

This paper proposes an H/H fault detection observer for discrete-time polytopic linear parameter-varying (LPV) system based on relative degree of output. First, a new output is generated by gathering the original output and its time shifted value. Then an H/H fault detection observer is designed for the new system such that the generated residual is robust against unknown disturbances and sensitive to actuator faults, simultaneously. In order to reduce some conservative-ness, the observer is solved by an iterative LMIs algorithm. Simulations results are given to illustrate the effectiveness of the proposed method.
