Abstract
A method controls a power split transmission structure to direct drive power from a drive through at least three interfaces to at least one output to supply connected consumers. The transmission structure has at least two variator paths each comprising a summation gearbox downstream of the interfaces in which drive power is varied via a mechanical and an electrical path. The transmission structure has power electronics or a hydraulic control device including at least three electric or hydraulic machines arranged in parallel with the summation gearbox of each variator path downstream of the interfaces. The method simultaneously controls the power electronics or a hydraulic control device and the electric or hydraulic machines in such a way that fluctuations in the power supply to the consumers are compensated for by the electric or hydraulic machines by regulating, via a control device, the summation gearbox of each of the variator paths and modifying a torque, a speed, or both, of the drive power via the power electronics system or the hydraulic control device.
