Vector control methods for induction machines: an overview

Abstract

In the last three decades, different vector control methods [field-oriented control (FOC), field acceleration method (FAM), universal field orientation (UFO), direct self control (DSC) and Takahashi method among others) have been proposed. It is difficult for students and nonspecialists to understand the drawbacks and advantages of each one. With this in mind, the objective of this paper is to propose a clear classification and comparison of them.

Field weakening implementation in AC induction machine predictive control

“…It is well known [1] that transformation of the AC induction machine model from the stationary αβ coordinates to the rotating reference frame dq oriented to the rotor flux space vector position leads to significant simplification of induction machine control design. The machine model (8), (11) can be transformed to the rotating reference frame using the Park's transform…”

“…As the induction machine is a non-linear system, its control is a quite complicated task. In past many algorithms of induction machine control were developed including frequency control, vector control [1], direct torque control [2], direct self control [3] and many of their modifications.…”

Adaptive sliding mode observer for induction motor using two-time-scale approach

“…Indeed, fluxes are usually estimated with measured stator currents, stator voltages, and motor speed by using the current model for rotor flux or voltage model for stator flux [9][10][11][12][13]. However, since the estimated fluxes are basically dependent on the motor model, variation in parameters inevitably propagates to flux estimation.…”

DSP Based Implementation of Field Oriented Control of Three-Phase Induction Motor Drives

“…In high performance drive systems, in which control variables include the torque developed in the motor, vector control (field orientation) technique are necessary [3]. Basic concept of field orientation that introduced by Hasse in 1969 and Blaschke in 1972, constitutes the most important paradigm in the theory and practice of induction motor.…”
