    • A microcomputer (an electric current command value calculating section) carries out field weakening control in which a d-axis electric current command value Id* is set to a negative value in correspondence with rotation angular velocity ω of a motor. The microcomputer determines whether an anomaly has occurred in an EPS. If it is determined that an anomaly is in a power supply system (step 202: YES), the microcomputer determines whether the anomaly in the power supply system is failure of electric current flow in any phase (step 203). If it is determined that electric current flow has failed in a certain phase, the microcomputer prohibits the field weakening control and outputs a motor control signal instructing to use two other phases free from the failure of electric current flow as electric current flowing phases (two phase drive mode, step 204).
    • 微型计算机(电流指令值运算部)对电动机的旋转角速度ω进行磁场削弱控制,其中d轴电流指令值Id *被设定为负值。 微机确定EPS中是否发生异常。 如果确定电源系统中出现异常(步骤202:是),则微计算机确定电源系统中的异常是否在任何阶段都有电流流失(步骤203)。 如果在一定阶段确定电流流动失败,则微机禁止弱磁控制,并输出指示使用没有电流流动故障的其他两相的电动机控制信号作为电流流动相(两相 驱动模式,步骤204)。

    • To present a motor drive control device capable of realizing high speed driving by a simple power feeding control method. The motor drive control device of the invention has a three-phase full bridge circuit for adjusting the feeding phase so as to invert the terminal voltage in feeding-off time, by cyclically repeating positive direction feeding period, non-feeding period, negative direction feeding period, and non-feeding period. In high speed driving, the phase is adjusted so as to invert the terminal voltage right after feeding-off, and if not reaching the desired rotating speed, the feeding time is shortened. As a result, the phase angle to the actual applied voltage can be advanced, and high seed rotation by weak-field system driving is realized. When there is a sufficient allowance in the voltage, the phase is adjusted so as to invert the terminal voltage immediately before turning on the feeding, and the feeding time width is adjusted so that the phase relation of the feeding-off time and the terminal voltage inverting time may be a desired relation and the applied voltage and the current phase are optimized, and the maximum efficiency driving is realized.

    • A speed estimation method for determining the speed of a sensorless permanent magnet brushless motor having one or more phases driven by one or more stages of an inverter, each stage including high- and low-switches connected in series across a DC Bus and having a respective common switched node, the respective switched node being coupled to a respective motor phase terminal. The method includes the steps of applying an alternating sequence of Zero Vectors to the inverter, the sequence alternating between a first Zero Vector whereby motor current does not flow in the DC Bus and a second Zero Vector wherein the high and low side switches of the inverter are alternately turned on with active vector components being injected by the inverter for each inverter stage thereby to allow motor current to flow in the DC Bus, whereby the terminals of the motor during the first and second Zero Vectors are shorted to brake the motor without substantially raising the voltage of the DC Bus during the braking time; and the speed of the motor can be determined by measuring the current in a sensor of the DC bus during the time when the second Zero Vector is applied without using a sensor in the motor.

    • A square wave voltage having an amplitude equal to an output voltage of a converter is applied to an AC motor by a square wave control block. Torque control of the AC motor is performed basically by changing the voltage phase of the square wave voltage according to the torque deviation. When the motor revolution is suddenly changed, a instruction value correction unit sets a voltage instruction value of the output voltage of the converter according to a change ratio of the motor revolutions. This improves control of the motor current by changing the voltage applied to the motor in accordance with the sudden change of the motor revolutions without waiting for torque feedback control having a low control response.
