Speed control of three phase induction motor using method hysteresis space vector pulse width modulation

Induction motor speed control was relatively difficult, because the generated torque and flux are related or not free. In addition to adjusting the speed, it required inverter control. The inverter output was not a pure sinusoidal signal but it is the result of the switching. Therefore, it was necessary to be able to fix the method of switching the inverter output signal that can adjust induction motor speed with load changes. This study applied the indirect method of vector control for setting the speed and incorporates methods of SVPWM (space vector pulse width modulation) with hysteresis then became hysteresis space vector pulse width modulation (HSVPWM) on the inverter. This study also reconstructed current signal. The setting speed three phase induction motor vector control using indirect methods were successfully applied. A change of pace on HSVPWM method successfully achieves the set point of 600 rpm with a rise time of 0.5267 seconds, 0.723 second steady state and has over shoot of 0.8%.

I. Introduction

Motors are one of the electric machines are most widely used in industry. Induction motor speed regulation in general can use the terminal voltage changes and frequency settings [1]. Induction motor a speed setting more difficult when using a DC motor, since the resulted of flux and torque has been related or not free. The factors that led to the induction motor control becomes more complex [2]. Vector control separates flux and rotor, this its setting is as well as DC motor [3].
