Induction Motor Field-Oriented Sensorless Control with Filter and Long Cable

In recent years, part of the efforts electric drive researcher has been focused on study sensorless control algorithms that allow controlling machine without a speed measure and with ever-fewer measurement devices. This article proposes possible solution for submarine application an asynchronous motor. The motor is designed to petrol pump at depth three thousand meters. fed by inverter located offshore platform, they are connected through filter cable 19.74 km long. this application, it not suitable use device; in fact, important as few components possible, order increase system reliability. A algorithm only needs available electrical measures proposed below.
