This paper proposes a new current vector control method that prevents voltage saturation by regulating the rate of pulse width modulation (PWM) in a flux weakening region according to a reference. While conventional methods use current limiting on both axes (d-axis and q-axis), our method stabilizes the current vector at onset to and within the flux weakening region using only q-axis current signal control. By eliminating the control of the d-axis current, the circuitry of the field programmable gate array (FPGA) is simplified. The effectiveness of the proposed method is verified through experiments of load fluctuations and supply voltage variations.
