This paper deals with the stabilization of a new open-loop unstable non-linear
biomechanical model to represent a person living with a spinal cord injury. The …

Few biomechanical models of sitting stability have been proposed over the last decades and
most of them control the trunk position through a lumbar torque. Unfortunately, this type of …

This paper is concerned with control design methods via a new Lyapunov function for fuzzy
descriptor systems. Takagi-Sugeno fuzzy descriptor model, that can represent nonlinear …

The design conditions for residual filter design, based on an unknown input observer
structure for linear discrete-time state-multiplicative linear systems, is presented in the paper …

En este trabajo de tesis se presenta el diseño de un esquema de control con el objetivo de
estabilizar la posición vertical de un péndulo H2AT (Head, 2 Arms and Trunk). Este sistema …

The performance of state estimation of discrete‐time Takagi–Sugeno systems is enhanced
by proposing a featured multiinstant united switch‐type observer. The novelty of the …

Sitting posture is different in subjects with spinal cord injury (SCI) compared to asymptomatic
subjects. This difference comes from the spine which, without muscular activity will bend …

This paper is concerned with the design of an application-oriented control law for a
biomechanical model of people living with spinal cord injury sitting stability. A major difficulty …

People living with a complete spinal cord injury (SCI) lose all sensibility and mobility below
their injury level. A complete injury located in the lumbar region would result in the loss of …
