Abstract
A motion control system of spraying machine based on FPGA, includes a motion controller. The motion controller includes an information analysis module, a speed control module and an interpolation module. The information analysis module is used for decoding the motion information to obtain the action information of the lance in a three-dimensional direction, and the rotation information of the clamp and the lance. The speed control module is used for driving the lance to a target position through the first motors according to the action information, and changing the speed of the interpolation movement of the lance in the three-dimensional direction into a trapezoid acceleration and deceleration. The interpolation module includes a first interpolation unit, a second interpolation unit and a control unit. The motion control system has high processing accuracy, fast reaction speed and good real-time performance.
