Global Stabilization of Induction Motor controller Based - Interconnected Observer

Abstract

In this paper, a sensorless speed control for induction machines (IM) is proposed. In order to improve the robust
properties of the controller, the control approach is synthesised based on the Lyapunov theory.
Moreover, an interconnected observer is presented to estimate the rotor speed.
Stability analysis of the closed loop system is developed and proved. Finally, simulation results have been presented in
order to exhibit the performances of the suggested control under parametric uncertainties
