A study on digital control of 3-D.O.F. BLDCM using LabVIEW

Abstract

In this paper, authors are proposed drive system for BLDCM using motor drivers based on LabVIEW. Most researchers generally use MATLAB/SIMULINK program as computer simulation tool for their control system design. These control system must be coded to the motor drivers using program language such as C for its verification. We developed drive system using LabVIEW, it is able to complete whole process from control system design to verification of control system without program coding. Authors also proposed power conversion stack designed for LabVIEW controller and BLDCM drive.motor drive system. All these features provide convenience to researchers who develop motor control system.In this paper, authors were developed and performed the spherical motor drive system using Labview on PXI platform considered real time programming in coil current control. The results showed that proposed drive system had good performance in the control of spherical motor. Fig. 1. Structure of the spherical motor II. SPHERICAL MOTOR AND ITS DRIVING PRINCIPLES
