Kurzfassung englisch:
This article describes considerations on a control structure for a
stepless electrical gear based on the Duomotor-principle[1]. The machine consists of one stator with a three phase winding and two permanent magnet excited synchronous rotors. In the discussed application one rotor acts as the input of mechanical energy, while the other one represents the output. The whole machine is controlled by one inverter, which itself is controlled by a signal processor system. The goal is to keep the amount of components at a low level. This means that for control purposes the rotor position has to be estimated without any mechanical sensor and that only one inverter for both rotors is used. Besides no electrical energy source shall be used. Therefore the electrical energy needed for the equipment must be generated within the equipment.
