Since it is no longer possible to increase the size of combine harvesters, increasing the machine efficiency is the only way to further raise the capacity. The most straightforward way to do so is to make every operator behave as the optimal operator, and this 24/7. This paper presents on a control system that regulates the speed of the combine harvester based on process variables such as feed rate, engine load and grain mass flow such that the capacity utilization is maximized at all times.
