Abstract
An arrangement for control of the drive speed of a harvester comprises an internal control loop for control of the drive speed of the harvester, to which can be sent a set value and an actual value of a throughput-dependent parameter, and also an external control loop to make available the set value of the throughput-dependent parameter for the internal control loop, to which set and actual values regarding the power output of a drive of the harvester can be sent as input parameters.

An arrangement for controlling a propulsion speed of a harvester, the arrangement comprising:
- an electronic controller that is connectable to a propulsion speed controller of the harvester, wherein the electronic controller includes an outer control loop for controlling the propulsion speed controller of the harvester, such that desired and actual values in respect of power of an internal combustion engine for driving the harvester are to be supplied as input variables to the outer control loop, and wherein the electronic controller is to control the propulsion speed controller of the harvester such that the actual value of the power of the internal combustion engine coincides with the desired value of the power of the internal combustion engine.
A system for controlling a propulsion speed of a harvester, the system comprising:
- an internal combustion engine;
- a drive operatively coupled to the internal combustion engine;
- and
- an electronic controller to control the propulsion speed of the harvester via the drive, the electronic controller including an outer control loop for controlling the propulsion speed of the harvester, such that desired and actual values in respect of power of the internal combustion engine for driving the harvester are to be supplied as input variables to the outer control loop, and wherein the electronic controller is to control the propulsion speed of the harvester such that the actual value of the power of the internal combustion engine coincides with the desired value of the power of the internal combustion engine
A method for controlling a propulsion speed of a harvester, the method comprising:
- providing desired and actual values of power of an internal combustion engine of the harvester as input variables to an outer control loop of an electronic controller;
- and
- controlling the propulsion speed of the harvester such that the actual value of the power of the internal combustion engine coincides with the desired value of the power of the internal combustion engine.
The method as defined in 29, further including providing signals of a motor controller of the internal combustion engine of a drive to the outer control loop as the actual value for power of the drive.
