Design of the Motion Control System in Chip Mounter

In order to realize the high performance of the motion control system of the chip mounter, a motion control system based on DSP FPGA was designed in this paper. The DSP module, as the core part of the motion control system, was used for achieving the function of the multi-axis coordinated motion and interpolation, as well as implementing the high-performance control algorithm. The optical encoder feedback signal of the system was applied to constitute a closed-loop control, and FPGA was used to extend encoder processing module to complete the encoder signal processing. Finally, experimental platform of servomotor was set up to assess the performance of the motion control system. The experimental has proved that the motion control system has high flexibility and real-time, and the system is applied for high-speed and high-precision motion control system.
