This paper describes a new solution to control the induction motor drive system without current sensors based on improving the Hysteresis Pulse Width Modulation technique. It has proposed a control scheme which uses stator currents estimated from the differential equation of state variables to replace the feedback signal from current sensors applied in the hysteresis current controller. To verify the proposed method, simulations in MATLAB/Simulink have been implemented in various operating conditions of the motor where its speed has been changed under load as well as no load conditions. The simulation results have demonstrated the effectiveness of the proposed control method for inductive motor drives.  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.

<p>Multilevel inverters (MLI) are becoming more popular over the years for medium and high power applications because of its significant merits over two level inverters. This paper presents an implementation of multicarrier based sinusoidal pulse width modulation technique for three phase seven level diode clamped multilevel inverter.  This topology is operated under phase opposition disposition pulse width modulation technique. The performance of three phase seven level diode clamped inverter is analyzed for induction motor (IM) load.  Simulation is performed using MATLAB/SIMULINK. Experimental results are presented to validate the effectiveness of the operation of the diode clamped multilevel inverter using field programmable gate array.</p>

Sinusoidal Pulse Width Modulation

This paper deals with the control of the induction motor using two different control methods: Space Vector and Sine wave pulse width modulation technique. The objective of the project is to find the most appropriate technique for induction motor control for industrial application. The scalar v/f method offers good performance only in the course of the steady-state and not under transient conditions. This important downside may be rectified by the vector control technique. The method provides high dynamic performance for velocity and torque-controlled AC machines

Modulation Methods

Inverter is an interface device between a dc source and ac loads which converts DC voltage to a variable voltage, variable frequency AC voltage. While converting, it introduces harmonics in the output of the system which results in additional heating of induction motors. Hence in order to diminish these harmonics, different techniques are introduced viz. external and internal control techniques in which the latter is more efficient. Out of the all proposed methods, the internal control of inverter which is also called as Pulse Width Modulation (PWM) can be achieved either using unipolar modulation technique or bipolar modulation technique. In this paper, the control circuitry to model unipolar and bipolar modulation methods is simulated and their performance is checked on an induction motor and compared in MATLAB Simulink environment.
