APPLICATION SPECIFIC SPEED IDENTIFICATION FOR INDUCTION MOTORS

Abstract

In this paper we describe and analyze an application specific speed and flux estimation method of induction motors. The technique utilizes the mechanical equation of the drive, assuming a certain load torque characteristic. The goal is to extend the stable operat-ing range towards the low speeds. The stability and the steady state performance of the method is investigated numerically and by simulation. The dynamic performance is verified by experiments and simulation.
