Abstract :
This paper proposes an on-line maximum efficiency control method for a dual-motor drive system. By using the on-line feedback signals and doing simple computations, the output torque of each motor can be determined. Then, a maximum efficiency operation of the whole system can be achieved. The efficiency of the whole system, which includes motor efficiency and inverter efficiency, is investigated. A digital signal processor TMS-320-F2808, made by Texas Instrument Company, is used as a control center to execute the required control algorithm. The proposed method is implemented on two identical surface-mounted PMSMs. Several experimental results can validate the correctness and feasibility of the proposed method. The proposed method can be used in industrial applications due to its simplicity.
