Survey on FPGA Based Space Vector PWMMotion Control

Abstract

The Space vector Pulse Width Modulation (SVPWM) is possibly one of the best techniques among all the PWM techniques for variable voltage variable frequency drives. This is a direct digital technique and space vector concept is utilized to calculate the duty cycles of inverter switching devices. Rapid growth in VLSI technology and EDA techniques has given way for the development of complex and compact controllers for industrial control systems. Specific hardware technologies such as FPGAs based architecture platforms provide rapid prototyping, high performance signal processing and flexibility for implementation of drive, motion and activation control of drives. This paper reviews some of the FPGA based SVPWM motor control systems available in the literature.
