    Abstract

    This paper addressed the design of a control system for a rotary threshing and separation system in a combine harvester. Utilising a distributed control architecture containing all observable crop flow parameters, the rotor speed is adjusted to maintain acceptable separation loss and grain damage using distributed impact sensors and a grain quality sensor (GQS). The GQS settling time for rotor changes is significantly reduced using a model based observer facilitating faster adjustment for grain losses in varying conditions.
