Abstract

The d-q model of Induction Motors (IMs) has been effectively used as an efficient method to analyze the performance of the induction machines. This study presents a step by step Matlab/Simulink implementation of a star-connected 3-phase IM under open-phase fault (faulty 3-phase IM) using d-q model. The presented technique in this paper can be simply implemented in one block and can be made available for control purposes. The simulated results provide to show the behavior of the star-connected 3-phase IM under open-phase fault condition.

Abstract

This paper proposes a novel method for speed control of three-phase Induction Motor (IM) which can be used for both healthy three-phase IM and three-phase IM under open-phase fault. The proposed fault-tolerant control system is derived from conventional Field-Oriented Control (FOC) algorithm with minor changes on it. The presented drive system is based on using an appropriate transformation matrix for the stator current variables. The presented method in this paper can be also used for speed control of single-phase IMs with two windings. The feasibility of the proposed strategy is verified by simulation results.

Abstract

This paper presents a technique for speed sensorless Rotor Flux Oriented Control (RFOC) of 3-phase Induction Motor (IM) under open-phase fault (unbalanced or faulty IM). The presented RFOC strategy is based on rotational transformation. An adaptive sliding mode control system with an adaptive switching gain is proposed instead of the speed PI controller. Using an adaptive sliding mode control causes the proposed speed sensorless RFOC drive system to become insensitive to uncertainties such as load disturbances and parameter variations. Moreover, with adaptation of the sliding switching gain, calculation of the system uncertainties upper bound is not needed. Finally, simulation results have been presented to confirm the good performance of the proposed method.DOI: http://dx.doi.org/10.11591/ijpeds.v4i3.6212

Abstract

This paper investigates the vector control of a star-connected three-phase Induction Motor (IM) under stator winding open-phase fault. The used vector control method is based upon indirect rotor field-orientation concepts that have been adapted for this type of machine. Beside the implementation of this method in critical industrial applications, the proposed method in this paper can be used for vector control of unbalanced 2-phase or single-phase IM with two main and auxiliary windings. Simulation results are provided to show the operation of the proposed drive system.

Abstract

Nowadays, Field-Oriented Control (FOC) strategies broadly used as a vector based controller for Single-Phase Induction Motors (SPIMs). This paper is focused on Direct Rotor FOC (DRFOC) of SPIM. In the proposed technique, transformation matrices are applied in order to control the motor by converting the unbalanced SPIM equations to the balanced equations (in this paper the SPIM with two different stator windings is considered). Besides this control technique, a method for speed estimation of SPIM based on Extended Kalman Filter (EKF) to achieve the higher performance of SPIM drive system is presented. Simulation results are provided to demonstrate the high performance of the presented techniques.DOI: http://dx.doi.org/10.11591/ijpeds.v4i4.6098

Abstract

The aim of this research is to provide a high performance vector control of single-phase Induction Motor (IM) drives. It is shown that in the rotating reference frame, the single-phase IM equations can be separated into forward and backward equations with the balanced structure. Based on this, a method for vector control of the single-phase IM, using two modified Rotor Field-Oriented Control (RFOC) algorithms is presented. In order to accommodate forward and backward rotor fluxes in the presented controller, an Extended Kalman Filter (EKF) with two different forward and backward currents that are switched interchangeably (switching forward and backward EKF), is proposed. Simulation results illustrate the effectiveness of the proposed algorithm.

Abstract

This article studies speed control of 3-phase Induction Motors (IMs) under fault conditions supplied by wind turbine using Indirect Vector Control (IVC). The wind turbine plays as a prime mover to a connected DC generator. Pulse Width Modulation (PWM) is used to obtain 3-phase AC voltage from the DC generator output. The proposed modified controller is able to control a star-connected 3-phase IM under normal, stator winding open-circuit fault and speed-sensor fault conditions. Simulation results are presented and shown the performance, validity and possibility of the proposed technique. The results demonstrate that, the proposed scheme provides good dynamic performance especially in reduction of IM speed and torque pulsations.
