An improved indirect field-oriented controller for the induction motor

IEEE Transactions on Control Systems Technology, 2003
In this paper, the standard indirect field-oriented controller (IFOC) commonly used in current-fed induction motor drives is modified to achieve global exponential rotor velocity/rotor flux tracking. The modifications to the IFOC scheme, which involve the injection of nonlinear terms into the current control input and the so-called desired rotor flux ...

Dynamics of Vector Control and Field Orientation

1996
Abstract The steady state analysis in Chapter 5 has been used to demonstrate the basic concepts of vector control and field orientation in both synchronous and induction machines. The underlying motivation in Chapter 5 was to obtain torque (and flux) control independent of motor speed.

Field-oriented control of an induction machine with winding asymmetries

2012 15th International Power Electronics and Motion Control Conference (EPE/PEMC), 2012
Modern electrical AC drives with best available performances are based on the so-called fundamental wave machine model approaches. This paper introduces an upgrade of fundamental wave model approach by respecting both inherent and fault-induced deviations of machine flux from its fundamental component.

Speed sensorless field orientation control of the induction machine

Conference Record of the 1991 IEEE Industry Applications Society Annual Meeting, 1993
A speed estimation method for an induction machine and its application to a flux observer-based field orientation (FOFO) control system proposed previously is presented. The motor speed is estimated on the basis of the difference between two flux estimators. The convergence of the method is analyzed, and a novel pole assignment method is proposed.

Parameter sensitivity of indirect universal field oriented controllers

PESC '91 Record 22nd Annual IEEE Power Electronics Specialists Conference, 1994
The universal field-oriented (UFO) controller was developed to decouple flux and torque in an arbitrary synchronous flux reference frame, realizing a high degree of generality which makes the UFO controller compatible with all existing field-oriented controllers, including indirect and direct field orientation.

Slip frequency detection for indirect field oriented control drives

Conference Record of the 2001 IEEE Industry Applications Conference. 36th IAS Annual Meeting (Cat. No.01CH37248), 2002
The paper presents a new technique to detect the slip angular frequency in induction motor drives based on indirect field oriented control. According to the proposed technique, the slip frequency is calculated by processing the effects exerted by an additional high frequency signal on the zero sequence stator voltage.

Dynamics in Vector Control and Field Orientation

2018
In Chap. 17 of Part III, vector control and field orientation have already been presented. However, the dynamics have not been analysed. In this chapter we discuss vector control and field orientation more thoroughly, including an analysis of their dynamic behaviour.

Reinforcement Learning-Based Controller for Field-Oriented Control of Induction Machine

2018
This paper presents the concept of reinforcement learning-based field-oriented control (FOC) of induction motor. Conventional controllers such as PID used for FOC of induction machines are model-based controllers and face the issue of parameter tuning.
