    • A drive control apparatus, which controls an AC motor subjected to rotational drive by applying a rectangular wave voltage thereto, comprising: an actual torque detection section for detecting an actual torque value T outputted from the AC motor; an estimated torque calculation section for calculating an estimated torque value Tm based on a motor model with the AC motor in a simulated state; and a voltage phase calculation section wherein the voltage phase calculation section calculates a first voltage phase φfb based on the actual torque value T and a command torque value T*, and a second voltage phase φff based on the estimated torque value Tm and the command torque value T* respectively, and outputs a value obtained by making the voltage phase subjected to weighting addition, as a voltage phase φv.
    • 一种驱动控制装置,其通过向其施加矩形波电压来控制经受旋转驱动的交流电动机,包括:实际转矩检测部分,用于检测从交流电动机输出的实际扭矩值T; 估计转矩计算部,用于基于具有模拟状态的交流电动机的电动机模型来计算推定转矩值Tm; 以及电压相位计算部,其中,电压相位计算部基于实际转矩值T和指令转矩值T *计算第一电压相位phifb,以及基于估计转矩值Tm和指令转矩的第二电压相位fiff 值T *,并输出通过使加权相加的电压相位获得的值作为电压相位。
