Design of a Multi-axis Motion Control Platform Based on LabVIEW’s Fuzzy Control Algorithm

This paper presents a fuzzy control algorithm applied to the position control of a multi-axis motion platform to achieve high precision motion control of the multi-axis motion platform. A LabVIEW-based multi-axis motion control system is designed. This system controls stepper motors using trapezoidal acceleration/deceleration pulse types and fuzzy control algorithms, which effectively avoids mechanical jitter and loss of step in the process of multi-angle motion of the stepper motor, and achieves accurate control of the stepper motor. The TCP/IP (transmission control protocol/internet protocol) communication protocol is used, so that data are output stably and not lost in the process of transmission and communication, achieving the purpose of interconnection of different systems and remote control of equipment. This control system has been tested to maintain a high level of stability and repeatability during actual operation.
