Integration of Scalar Control in Space Vector Pulse-Width Modulation for robust motion controller

Abstract

This paper proposes an architecture based on Space Vector Pulse-Width Modulation (SVPWM) for fault-tolerant motor controller. The proposed architecture integrates Scalar Control with SVPWM to increase area-efficiency and functionality of the module. The implementation on Field Programmable Gate Array (FPGA) using Verilog increase the area utilization to only 1.5 times compared to the SVPWM and maximum operating frequency of around 60 MHz. The functionality of the design is tested in simulation for constant and variable motor speed and has shown a promising result with error of 0.97% for constant speed and 1.98% for variable speed. Based on the result, the proposed architecture for SVPWM with Scalar Control capability is proven to be a viable option for fault-tolerant design for motor controller when the feedback is absent.
