Design and Control of an Assistive Device for the Study of the Post-stroke Sit-To-Stand Movement

Benyamine Allouche, Amal Saadé, Antoine Dequidt, Laurent Vermeiren, Olivier Rémy-Néris

Every year more than 5 million people worldwide become hemiplegic as a direct consequence of stroke. This neurological deficiency, often leads to a partial or a total loss of standing up abilities and /or ambulation skills. In order to propose new supporting solutions lying between the wheelchair…

Virtual strain gauge based on a fuzzy discrete angular domain observer: Application to engine and clutch torque estimation issues

Rémi Losero, Jimmy Lauber, Thierry-Marie Guerra

In many real time applications, information of transmitted torque is a mandatory input of the embedded control strategies. In the most of cases, the use of a physical torque sensor (strain gauge) is compromised by cost and bulk reasons and the torque is not measured. Unfortunately, the need of an…

Multi-Sensor Fusion for Obstacle Detection and Recognition: A Belief-Based Approach

Mokhtar Bouain, Denis Berdjag, Nizar Fakhfakh, Rabie Ben Atitallah

This paper presents an obstacle detection and classification method for intelligent vehicles. We use both a camera and radar in a multi-sensor perception framework. Our main goal is to improve the reliability of pedestrian and vehicle recognition of the system, avoiding false alarms and reducing…

Input-Constrained LPV Output Feedback Control for Path Following of Autonomous Ground Vehicles

Tran Anh-Tu Nguyen, Hui Zhang, Chouki Sentouh, Jean-Christophe Popieul

We discuss a new control method for path following of autonomous ground vehicles. First, the nonlinear vehicle system is transformed into a polytopic LPV model allowing to handle a large variation range of vehicle speed with a reasonable numerical complexity. Second, based on an LPV static output…

Reinforcement Learning for Energy Optimization Under Human Fatigue Constraints of Power-Assisted Wheelchairs

Guoxi Feng, Lucian Busoniu, Thierry-Marie Guerra, Sami Mohammad

In the last decade, Power-Assisted Wheelchairs (PAWs) have been widely used for improving the mobility of disabled persons. The main advantage of PAWs is that users can keep a suitable physical activity. Moreover, the metabolic-electrical energy hybridization of PAWs provides more flexibility for…

Transforming variable transport delays into fixed ones: An application to a conveyor belt problem

Thomas Josso-Laurain, Zsofia Lendek, Jimmy Lauber, Reinaldo Martinez Palhares

This paper presents a systematic methodology to deal with variable transport delays by constructing a new discrete domain where the delay becomes fixed (a difference of samples). The Euler transformation is used to change from the continuous-time domain to this special discrete domain depending on…
