摘要: The paper deals with the vector control of two surface-mounted permanent-magnet (PM) synchronous-motors in configuration “single-inverter dual-motor”, operating also unbalanced loads. Since this structure is justified by objective obtaining low cost drives, a computation burden sensorless method proposed order to further reduce system complexity. A very simple algorithm for position/speed estimation coupled hybrid adaptive Phase-Locked Loop indeed sufficient achieve satisfactory results heavy transient operations. Furthermore, novel strategy conceived reference an “equivalent” motor, whose rotor position average separately evaluated positions PM motors. technique validated extensive numerical campaign.
