High order sliding mode controller and adaptative interconnected observer
Résumé
An adaptive interconnected observer and high order sliding mode control of induction motors without mechanical sensors (speed sensor and load torque sensor) are proposed and experimentally evaluated. \noindent The adaptive interconnected observer estimates fluxes, angular velocity, load torque and the stator resistance. Stability based on Lyapunov theory is proved to guarantee the "observer-controller" stability.
