Integrated control system construction for electromagnetic system based on Lab VIEW

The electromagnetic system is driven by multiple programmable power supplies manipulating the micro-robot. Robot movement is observed and analyzed through CCD camera in real time. Thus, the driven force could be adjusted accordingly. An integrated system based on LabViewwas proposed in this paper, combining the visual feedback system and electromagnetic coils system, which realizes the analysis of robot motion state and the real-time control of the programmable power supplies. Experiment on the linear motion of magnetic microbead is constructed for pretest and preliminary calibration. Furthermore, PID control strategy was used for driving the microbead moving along a circular path. The integrated control system simplifies the operation of the electromagnetic driven system and provides a basic platform for executing more precise control algorithms subsequently.
