    • The technique of the present invention sets a torque voltage to be applied to a motor in response to a required torque and adjusts the duty of an inverter to ensure application of the torque voltage according to the observed voltage of a battery. In a motor controller constructed to attain such control, before a start-up of normal operation of the motor, a fixed duty is set for switching the inverter to apply a voltage to the motor. The value of electric current running in response to the applied voltage is measured. The mapping of the value of electric current to the source voltage in the case of switching the inverter at a fixed duty is stored in advance in the form of a table. The procedure reads the true value of the source voltage from the table and thereby specifies an offset error occurring in a voltage sensor of the battery. The procedure then corrects the observed voltage of the battery and adequately regulates the torque voltage.

    • A drive control apparatus and method drives an AC motor by applying a rectangular wave voltage thereto. The apparatus estimates the torque of a rotor of the AC motor, and detects a torque deviation which is the difference between the estimated torque and a required torque of the motor. A controller controls a state of the rectangular wave voltage applied to the AC motor, through torque feedback control based on the torque deviation, so that the torque approaches the torque command value. The controller detects a current rotation speed of the motor, and switches, in a predetermined order, a plurality of predetermined rectangular wave voltage states corresponding to different phase values of the rectangular wave voltage. The switching timing of the rectangular wave voltage states is set to a timing that deviates from a reference timing determined based on the current rotation speed, by a length of time corresponding to the torque deviation.
    • 驱动控制装置和方法通过向其施加矩形波电压来驱动AC电动机。 该装置估计交流电动机的转子的转矩,并且检测作为该电动机的推定转矩与所需转矩之差的转矩偏差。 控制器通过基于扭矩偏差的转矩反馈控制来控制施加到AC电动机的矩形波电压的状态,使得转矩接近转矩指令值。 控制器检测电动机的当前转速,并且以预定顺序切换与矩形波电压的不同相位值对应的多个预定矩形波电压状态。 矩形波电压状态的切换定时被设定为与基于当前转速确定的基准定时相对应于扭矩偏差的时间长度的定时。
