  • Publication number: 20040060273
    Abstract: A forage harvester includes feed rolls operable to convey crop to a crop cutter drum. The forage harvester is provided with a control arranged to produce a controller output signal based upon a sensed number of rotations of the crop cutter drum or the feed rolls. The controller output signal operates such that a difference between an actual relation between the feed roll and cutter drum speeds and a nominal relation is at least reduced. The control is operable to produce the controller output signal independent from a detection of the speed of the feed rolls or the chopper drum. The speed of the feed rolls or chopper drum is hence controlled without feedback, but with an open loop. Thus, a sensor is saved and control oscillations are avoided.

  • Patent number: 6431127
    Abstract: A ventilation device of an agricultural vehicle such as a combine, forage harvester or tractor having an engine (10) and a cooling device (12) for cooling the engine (10) and/or additional parts to be cooled that are in a heat conducting relationship. The ventilation device comprises a fan (20) a fan drive (18) and a control system (26) connected to the fan drive (18) to regulate the feeding rate of the fan (20). The control system (26) is arranged to control the fan drive (18) in the most energy-efficient way while making allowance for the amount of ambient air required by the cooling device (12) and the drive power requirements of the fan (20) using a flat logic (fuzzy control).
