Virtual instrument system is up-to-date computer technology and equipment, product of the combination of technologies. It uses powerful computer systems, combined with dedicated hardware, to breakthrough the limitations in traditional data-processing equipment, display, transmission, storage and others . So have the needs of virtual instrument technology hardware and software in order to minimize system cost and increase system functionality and flexibility, allowing users in the general-purpose computer platform could be better to define their own needs and design functions of the measurement apparatus, its core technology is a virtual instrument software.
This article is based on virtual instrument technology for DC motor speed measurement, control, and the PID through LabVIEW Toolkit awakened to the DC motor control, so that rotation of computer automatic control system. And the design of workstations using NIELVIS platform and LabVIEW software DAQ devices to achieve a combination of hardware and software, and ultimately to the DC motor speed measurement and control.
