“…It was proved that the controller delivered precise speed control. Moreover, [14] showed that harmonics contents and starting current reductions with good motor efficiency was delivered by microcontroller based 3 ɸ space vector pulse width modulation technique, which was introduced in this study to obtain constant V/F ratio. A comparison between tow pulse width modulation techniques including sinusoidal and space vector techniques was conductedin [15].…”

Induction motor has been widely applied in many sectors, as it has the advantages of simplicity, toughness and can withstand hard environment conditions. The working of such motor in constant voltage/frequency (V/F) speed control method has been popular since the introduction of the power electronic devices, which consequently make the implementation of this method simpler and effectives. The V/F speed control is dominated choice for many applications, especially open loop control and also for closed loop control when the accuracy is not a crucial issue. This study deals with two cases of controlling open and close of the electronic switches. The first with equal intervals by placing regular pulses at the opening and closing periods, and the second using three-phase pulse width generator, through which the control of different periods is carried out according to the required control. Four models have been simulated in this study including, three-phase induction motor at constant torque (constant load) as well as at variable torque (variable load), modeling of PWM-VSI for three-phase induction motor at constant torque (constant load) as well as at variable torque (variable load). The results have shown that speed profile of the IM can be improved by controlling the invertor using PWM technique.

“…It is difficult to control speed because the flux and torque in the induction motor are coupled i.e., they are not independently controlled as in the case of the direct current (DC) motors in which the torque and flux producing components are independent of each other (Biswal and Satpathy, 2021). The advent of power electronic converters and fast digital signal processors now makes it easier to control induction motor speed (Richardson, Patterson and Parchment, 2021;Jafari, et al, 2021;Alahmad and Kaçar, 2021). Instead of driving the induction motor directly from the AC mains, it can now be driven from power converters that are capable of varying the magnitude, frequency and phase angle of the voltage applied to the motor according to certain control algorithms in order to bring about a desired change in torque and hence speed of the motor (Abad, 2017;Umar, Akbar and Kazmi, 2018;Hareesh and Jayanand, 2021).…”

“…Many speed control strategies have therefore been developed over the last two decades that take advantage of advances in semiconductor technologies, pulse width modulation techniques and control algorithms (Richardson et al, 2021;Sahu, Mohanty and Mishra, 2021;Zand et al, 2021). The result manifests in the increasing areas of applications for the existing induction motors.…”

Three-phase Induction motors are increasingly used in a variety of applications such as fans, milling machines, transportation, etc. In applications requiring precise speed control such as robotics, centrifugal pumps, mills and other high-performance applications, it is essential that speed is maintained constant at a desired fixed value. Many speed control techniques exist in literature but this paper presents the design of a simple PI controller and its use to control the speed of a three-phase induction motor. A controller design that applies the Phase margin (PM) as the stability criterion is employed. The cross-over frequency and phase margin of the open loop gain of motor and controller are specified in order to develop a stable control system. The three-phase induction motor model is presented and modified for the purpose of control. A comparative analysis between the motor performance with and without the PI controller was performed. The unit step response of the speed control loop is characterized by rise time, settling time, steady state error and peak overshoot of 0.0253s, 0.19s, 2.2e-14% and 24.03% respectively. Simulation results show that the speed of the uncontrolled motor changed whereas that of the controlled motor returned quickly to its initial value after the motor is subjected to load disturbances in steady state.Keywords— Controller, Induction motor, Model, Speed control, Steady state.
