Circular Interpolation Trajectory Control of Manipulator Based on LabVIEW

Aiming at the arc trajectory control of manipulator, a simulation control based on LabVIEW is proposed to verify the effectiveness of the algorithm. This design is controlled by PC, connected with stepping motor through PCI bus, and the operation interface on PC is written by LabVIEW. This paper briefly summarizes the characteristics of virtual instrument technology LabVIEW software, designs a simple control system of stepping motor by using LabVIEW graphic programming language, and introduces the general process and method of virtual instrument programming. The system designed with LabVIEW has the characteristics of flexible control, strong man-machine interaction, friendly interface and convenient operation. The design of this system finds a common method for the design of virtual instrument.
