1. An arrangement for controlling a propulsion speed of a harvester, the arrangement comprising:
an electronic controller configured to control the propulsion speed of the harvester,
wherein the electronic controller includes an outer control loop operating at a first cycle time duration and an inner control loop operating at a second cycle time duration shorter than the first cycle time duration,
wherein the outer control loop is configured to control the propulsion speed of the harvester, such that a desired power value and an actual power value with respect to power of an internal combustion engine for driving the harvester are supplied as input variables to the outer control loop,
wherein the inner control loop is supplied with a desired variable value and an actual variable value of a throughput-dependent variable from the outer control loop, and
wherein the electronic controller is configured to control the propulsion speed of the harvester such that the actual power value coincides with the desired power value.
