The main purpose of this paper is to develop a high-level performance, and low-cost current sensorless control strategy for Induction Motor (IM) drives. Therefore, new phase-current regeneration method, vector in induction motor drives introduced. idea based on the reconfiguration Luenberger adaptive observer currents estimation, using information provided by dc-link voltage sensor. basis propo...

The area of multiphase variable-speed motor drives in general and multiphase induction motor drives in particular has experienced a substantial growth since the beginning of this century. Research has been conducted worldwide and numerous interesting developments have been reported in the literature. An attempt is made to provide a detailed overview of the current state-of-the-art in this area....

Main flux saturation in induction machines plays an important role in a number of operating regimes and therefore has to be accounted for in the process of modelling. The current state space model of a saturated induction machine has gained substantial popularity recently as an excellent tool for transient and steady-state time domain analysis of induction motor drives when the main flux satura...

In this paper, Direct Torque Control (DTC) approaches of induction motor (IM) drives has been proposed and it is extensively implemented in industrial variable speed applications. This paper presents a unique direct torque control (DTC) approach for induction motor (IM) drives fed by using a fuzzy logic controller. The intention is to develop a low-ripple high-performance induction motor (IM) d...

An electric drive is an industrial system which performs the conversion of electrical energy to mechanical energy (in motoring) or vice versa (in generator braking) for running various processes such as: production plants, transportation of people or goods, home appliances, pumps, air compressors, computer disc drives, robots, music or image players etc. About 50% of electrical energy produced ...

AC drives are employed mainly in process plants for various applications. In most industrial applications, Induction motor preferred as they robust, reliable, and efficient. Process industries have seen a paradigm shift from manual control to automatic control. Advancements power electronics technology led smooth of the induction using variable frequency over an entire speed range. Variable Fre...

This paper presents a modeling and analysis of multi-phase inverter fed multi-phase induction motor drive with different number of phases. Multiphase induction motor drives possess several advantages over conventional three-phase drives such as lower torque pulsation, fault tolerance, stability, high efficiency and lower current ripple and reduced current per phase without increasing voltage pe...
