Book excerpt: The method by which automation of agricultural machinery can be developed is illustrated in the case of cereal combine harvesting. The controlled variables are machine forward speed and threshing cylinder peripheral speed. Four control systems have been developed that optimise these speeds on the basis of harvest costs minimisation, which includes variable and fixed costs of the machine and those of machine- and timeliness losses. The evaluated systems make use of a varying number of input process variables and control the machine speed exclusively, or both machine speed and threshing speed. The financial benefits from these control systems were calculated by means of a computer simulation. The research required in developing the models and control systems is discussed in detail. The simulation results demonstrate that control of low-frequency variations in crop properties brings some slight benefit and indicate that timeliness losses are of great importance to optimisation..
