Research and Development of a Four-Axis FPGA-Based Motion Control Platform
By analyzing the problems on control system of 6-DOF parallel robot, this paper presents a 4axes motion control platform based on FPGA. With a structure of MCU+FPGA, this platform communicates with user interface (UI) on PC through USB. As the core of the platform, the FPGA-based 4-axes motion controller can implement interpolation on hardware, such as linear interpolation, circular interpolation, and bit pattern interpolation. So it resolves desynchrony of the multi-axis linked motion that was only implemented by software interpolation on PC, hence improves the trace precision. Through analyzing the design of the three main parts of the motion control platform, 4axis motion controller, microstepping driver for stepping motor, and USB bus, this paper delves into the basic structure and working principle of the platform. The performance of the motion control platform is analyzed through actual test and simulation, and the control scheme has constructive reference for independent self-development of motion controller.
