Adaptive observer design for a class of nonlinear systems with time delays

by Ahlem Sassi, Michel Zasadzinksi, Harouna Souley Ali and Kamel Abderrahim

Advances in Science, Technology and Engineering Systems Journal, Volume 3, Issue 1, Page # 373–383, 2018; DOI: 10.25046/aj030146

Abstract:

This paper deals with the design of adaptive observer for a class of nonlinear systems with time delays. Within this work, we develop an adaptive observer for a bilinear time delay system, then we extend those results in the presence of Lipschitz nonlinear functions in the system’s dynamics. In the stability analysis of the estimation…

Actuator Fault Reconstruction based Adaptive Polytopic Observer for a Class of Continuous-Time LPV Systems

by Radhia Houimli, Neila Bedioui and Mongi Besbes

Advances in Science, Technology and Engineering Systems Journal, Volume 3, Issue 1, Page # 443–450, 2018; DOI: 10.25046/aj030154

Abstract:

This paper is an extension of work originally presented in conference name. The goal is to propose new fault detection and fault isolation techniques for a polytypic linear parameter-varying system (LPV). In this work, an adaptive observer design is formulated for a given polyquadratic Lyapunov function. Subsequently, new sufficient conditions are given in terms of…
