The paper presents an improving speed control method using a field-oriented control (FOC) technique for the hysteresis current (HC) controller in the induction motor drive. The basic principle of a controller applying hysteresis band current is comparing reference currents and the measured currents to generate switching pulses for controlling an inverter. In the typical FOC for the HC controller, the rotor flux angle’s value will increase to infinity due to the integral algorithm’s error accumulation. This problem can lead to the faulty operation of the induction motor drive (IMD) system. In this paper, a current model with the advantage of precisely determining the periodic rotor flux angle is used in the FOC technique to provide reference currents for the current controller. The rotor flux angle will periodically change according to the motor speed in the range [-π π] during the operation of IMD. The operation of the induction motor drive is implemented and tested by MATLAB/SIMULINK software. The simulation results have demonstrated the effectiveness of the HC control method-based FOC technique with periodic rotor flux angle in controlling motor speed. This is an Open Access article distributed under the terms of the Creative Commons Attribution License (http://creativecommons.org/licenses/by/4.0/), which permits unrestricted use, distribution, and reproduction in any medium provided the original work is properly cited.

This paper presents design and implementation of scalar control for 3 phase induction motor. This method leads to be able to adjust the speed of the motor by control the frequency and amplitude of the stator voltage of 3 phase induction motor, the ratio of stator voltage to frequency should be kept constant, which is called as V/F or scalar control of 3 phase induction motor drive. The proposed control system is used to generate control signals to overcome the nonlinear dynamics of 3 phase induction motor. Simulation results show that the 3 phase induction motor is able to track the frequency input shift via inverter with 50 Hz frequency get speed 2090.8 rpm.

This paper introduces a direct model predictive voltage control (DMP VC) for a sensorless five-phase induction motor drive. The operation of the proposed sensorless DMP VC is based on the direct control of the applied stator voltages instead of controlling the torque and flux as in model predictive direct torque control (MP DTC). Thus, the simplicity of the control system is enhanced, which saves the computational time and reduces the commutation losses as well. The methodology based on which the proposed sensorless DMP VC performs its operation depends on minimizing a cost function that calculates the error between the reference and actual values of the direct and quadrature (d-q) axes components of stator voltages. The reference values of d-q components of stator voltages are obtained through incorporating the deadbeat control within the proposed model predictive system. A robust back-stepping observer is proposed for estimating the speed, stator currents, rotor flux, and rotor resistance. The validity of the proposed sensorless DMP VC is confirmed through performing detailed and extensive comparisons between the proposed DMP VC and MP DTC approach. The obtained results state that the drive is exhibiting better performance under the proposed DMP VC with less ripples content and reduced computational burden. Moreover, the proposed back-stepping observer has confirmed its effectiveness in estimating the speed and other variables for a wide range of speed operation.
