In this paper, the planar two degree of freedom manipulator is taken as the research object. Based on the LabVIEW platform and the PID algorithm, the trajectory tracking control of the manipulator is carried out. The system is based on NI CompactRIO platform and PC built the hardware platform of the system, using the graphical programming language LabVIEW control software programming and the establishment of manmachine interface, realizes the manipulator a predetermined trajectory tracking control function. Through the experiment of the two degrees of freedom manipulator in reality, the angle error curve of the end of the manipulator was obtained in the front panel window of LabVIEW. The experimental results show that the plane trajectory, two DOF Manipulator designed the tracking control effect is good, can meet the requirements of industrial field control.
