A sufficient condition to design unknown input observers for nonlinear systems with arbitrary relative degree

Pedro Coutinho, Iury Bessa, Wen‐bo Xie, Tran Anh-Tu Nguyen, Reinaldo Martínez Palhares

Abstract This article addresses the problem of state and unknown inputs (UIs) estimation for nonlinear systems with arbitrary relative degree with respect to the UIs. For this purpose, a novel nonlinear unknown input observer (UIO) is proposed, which is able to decouple the UIs by using the...

Cascade Takagi–Sugeno fuzzy observer design for nonlinear uncertain systems with unknown inputs: A sliding mode approach

Cuong Nguyen, Anh‐tu Nguyen, Sebastien Delprat

This article investigates the design of Takagi–Sugeno (TS) fuzzy model-based observers for nonlinear systems with parametric uncertainties and unknown inputs. To address this challenging problem, two observers are constructed in cascade. Based on the sliding mode technique, the first observer...

Zonotopic observer designs for uncertain Takagi–Sugeno fuzzy systems

Masoud Pourasghar, Tran Anh-Tu Nguyen, Thierry-Marie Guerra

This paper addresses the zonotopic observer design for nonlinear systems affected by uncertainties, i.e., state disturbances and measurement noises using Takagi–Sugeno (TS) fuzzy technique. The system uncertainties are considered as unknown but bounded, which are handled via a set-membership...

Time scale reachability and controllability of time‐varying linear systems

Bacem Ben Nasser, Mohamed Djemai, Michael Defoort, Taous‐meriem Laleg-Kirati

In this paper, we investigate the analysis of reachability and controllability for time-varying linear systems evolving on nonuniform time domains also known as arbitrary time scales. Based on appropriate operators, some necessary and sufficient conditions are derived to guarantee the reachability...

Membership Functions Integration Approach for State Feedback Control of T-S Fuzzy Systems

Wen-Bo Xie, Bo-Lin Xu, Chen Peng, Anh-Tu Nguyen

For the stability analysis problem of a T-S fuzzy system, a membership functions integration-based method is proposed to relax the existing conservatism. Firstly, indefinite integral functions are derived for the membership functions. Then with a piecewise linear approximation approach, the...

Adaptive robust finite-time tracking control for quadrotor subject to disturbances

Yakoub Nettari, Moussa Labbadi, Serkan Kurt

Quadrotors are extremely agile UAVs with many unknowns regarding their moment of inertia, drag coefficients, and mass. Aside from aerodynamic turbulence, the quadrotor has a high level of nonlinearity due to its underactuated mechanical system. These last two factors cause issues that necessitate...

The rehabilitation robot: factors influencing its use, advantages and limitations in clinical rehabilitation.

Nawel Ouendi, Remy Hubaut, Sylvie Pelayo, Françoise Anceaux, Laura Wallard

Purpose Despite the proven effectiveness of rehabilitation robots (RR) in the literature, they are still little used in clinical rehabilitation. The aim of this study was to analyse the factors influencing the use of RR and the perception of therapists who used RR. Method In order to characterize...
