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...

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...

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...

Time scale observability and constructibility of linear dynamic equations

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

This paper investigates the observability and constructibility problems of time-varying linear dynamic equations using time scale theory. First, we define observability, reachability and constructibility operators on time scales. Some necessary and sufficient conditions are proposed to ensure the...

Stabilization of a class of stochastic nonlinear systems using a bang‐bang controller

Asma Barbata, Michel Zasadzinski, Harouna Souley Ali

In this article, a bang-bang control strategy is proposed to almost surely exponentially stabilize a class of nonlinear stochastic systems driven by multiplicative noises. Two cases are considered: first, a state feedback control if the whole state is measured and, second, an observer-based...
