LabVIEW-base automatic rising and falling speed control of stepper motor

Stepper motor is widely used as controlling and driving machine in opening loop controlling system. As high speed moving, stepper motor must have rising and falling process avoiding losing step and over step. In this paper, based on analyzing and comparing some controlling graph, it gives a LabVIEW-based stepper motor control method and the composition of the control system, and making the soft controlling of stepper motor´s automatic rising and falling speed come true. Comparing with the single-chip controlled stepper motor, this system based on LabVIEW has a good interface, the easy programming to effective control, that is the practical application value.
