H2/H∞ Multiobjectives for Fault Detection in Uncertain Polytopic Systems ⋆
نویسنده
چکیده
Abstract: This paper presents a novel technique for robust fault detection, based on a modified H2/H∞ performance condition, which is described as LMI. Some theoretical results are shown in order to synthesize the residual generation scheme, for systems subjected to parametric uncertainty. The uncertainty parameters are supposed to belong to a polytope. The extended H2/H∞ conditions are obtained by means of the well known projection lemma. Fault detection and isolation are done by using a filters bank (i.e. multifiltering) based on Luenberger’s observer and one filter is obtained for each fault. Performance of the proposed synthesis technique is illustrated by a numerical example.

In this article, a new approach is proposed to design robust switching gain-scheduled dynamic output feedback control for switched uncertain continuous-time linear parameter varying (LPV) systems. The proposed robust switching gain-scheduled controllers are robustly designed so that the stability and H2-gain performance of the switched closed-loop uncertain LPV system can be guaranteed even und...
متن کاملGeneral polynomial parameter-dependent Lyapunov functions for polytopic uncertain systems
New LMI conditions are given for robust H2 analysis of polytopic systems based on polynomial parameter-dependent Lyapunov functions. Results are derived using a ”slack variables” approach. Numerical results illustrate the characteristics of the proposed results in terms of conservatism reduction and numerical complexity.

A particular class of uncertain linear discrete-time periodic systems is considered. The problem of robust stabilization of real polytopic linear discrete-time periodic systems via a periodic state-feedback control law is tackled here, along with H2 performance optimization. Using additional slack variables and the periodic Lyapunov lemma, an extended sufficient condition of robust H2 stabiliza...
متن کاملAn LPV Approach to Sensor Fault Diagnosis of Robotic Arm
One of the major challenges in robotic arms is to diagnosis sensor fault. To address this challenge, this paper presents an LPV approach. Initially, the dynamics of a two-link manipulator is modelled with a polytopic linear parameter varying structure and then by using a descriptor system approach and a robust design of a suitable unknown input observer by means of pole placement method along w...
