A system for controlling an operative parameter of a harvesting header of an agricultural harvesting machine comprises a first sensing arrangement for sensing a property of a field in front of the header in a contact-less manner, a second sensing arrangement for providing a signal suited to derive a value of an adjustable work parameter of the header, an actuator for adjusting the work parameter, and a control unit for determining a control signal for the actuator based on the signal from the first sensing arrangement and on the signal from the second sensing arrangement. The second sensing arrangement is arranged to detect the position of a reference point, which indicates the work parameter, in a contact-less manner, and that the first sensing arrangement and the second sensing arrangement are relatively fixed.

An overall machine operational state (such as a problem state, field state, machine state, other non-problem state, etc.) is identified, and exit and entry conditions are monitored to determine whether the machine transitions into another operational state. When the machine transitions into a problem state, a multiple input, multiple output control system uses a state machine to identify the problem state and a solution is identified. The solution is indicative of machine settings that will return the machine to an acceptable, operational state. Control signals are generated to modify the machine settings based on the identified solution.
