Abstract :
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. The adaptive interconnected observer estimates fluxes, angular velocity, load torque, and stator resistance. Stability based on Lyapunov theory is proved to guarantee the ldquoobserver-controllerrdquo stability.
