Stability and stabilization of a flexible manipulator


Aicha Elhsoumi, Rafika El Harabi, Saloua Bel Hadj Ali and Mohamed Naceur Abdelkrim

In this paper, the stability and stabilization of a neutral system with time-delay are treated. First, the flexible manipulator is modeled as a neutral time-delay system form. Then, based on the Lyapunov-Krasovskii functional theory, a delay dependant condition is proposed to test studied system stability, which is applied to a flexible manipulator model. The test shows that this flexible manipulator is instable and it should be stabilized. For this reason, other theorem is elaborated to determinate a feedback control based on linear matrix inequalities (LMI). Finally, simulation results are presented to prove theorical development.

Keywords: Flexible Manipulator, Stability, Stabilization, LMI, Lyapunov-Krasovskii.
