Aim at stepper motor are more and more extensive used in machine tools and the automatic record appearance etc, passing to adopt the LabVIEW program to develop the control system based on virtual instrument technique for stepper motor, the control system are used the method of software time-lapse and the accelerate and decelerate model to control the rotate speed and the position of stepper motor.
The control system based on virtual instrument technique for stepper motor have fine software interface and there is a good performance in the aspects of control. LabVIEW program raised the development efficiency on the very big degree. The A/D conversion machine, the D/A conversion machine and count etc are collected in the integral whole of data acquisition card. The hardware contracts the structure physical volume, economizes the cost, shows a good applied foreground.
Key words stepper motor LabVIEW the rotate speed control
the position control
