Abstract
A control system for a material spreading machine pre-determines a machine velocity trajectory plan so that the velocity and acceleration of the machine down the spreading table can be controlled in real time. The control system includes encoders which provide real time information as to the actual machine velocity and material feed rate so that dynamic feedback and control of the spread can be maintained. Data from the machine velocity encoder is used to calculate the actual position of the machine along the table during the spread.
