摘要： If the magnitude of a voltage command vector to a motor driver is smaller than a preset value in a control period, in each of a predetermined number of subsequent control periods (a compensation period), a pulse voltage vector is added to the voltage command vector so as to make substantially zero the average value of the added pulse voltage vectors during the compensation periods, and the compensated voltage command vector is used for the subsequent calculation. Also, two direction data for each phase winding are stored at the center of each of the two dead times following the edges of a voltage command pulse in each control period. An estimated phase voltage is calculated from the last voltage command pulse width, a phase voltage fluctuation during the two dead time of each control period and the stored direction data. The rotor position angle is precisely calculated from the estimated phase voltage.

摘要： A sensor-less control apparatus is designed for a permanent magnet synchronous motor having multiple-phase armature windings and a rotor. The sensor-less control apparatus includes a first device for calculating a rotational angle and an angular velocity of the rotor from phase currents and phase voltages of the armature windings. A second device is operative for controlling energizations of the armature windings in response to the rotational angle and the angular velocity calculated by the first device. A third device is operative for correcting the rotational angle calculated by the first device into a correction-resultant rotational angle and informing the second device of the correction-resultant rotational angle, and for feeding back information of the correction-resultant rotational angle to the first device. A fourth device contained in the third device is operative for low-pass-filtering the rotational angle calculated by the first device and changing the rotational angle into a filtering-resultant rotational angle. A fifth device contained in the third device for, in cases where a previous rotational angle outputted from the fourth device and the rotational angle calculated by the first device are not in a same period, correcting the previous rotational angle into a correction-resultant previous rotational angle and informing the fourth device of the correction-resultant previous rotational angle.

摘要： A permanent magnet synchronous motor having multiple-phase armature windings and a rotor is subjected to sensor-less control. Phase voltages are generated in response to voltage command values. The generated phase voltages are applied to the armature windings. Phase currents through the armature windings are detected. The detected phase currents depend on the voltage command values. An angular position and an angular velocity of the rotor are calculated from the detected phase currents. The voltage command values are adjusted in response to the calculated angular position and the calculated angular velocity of the rotor to implement feedback control of the motor. An angular velocity of the rotor is estimated from a time-domain variation in the calculated angular position of the rotor. A determination is made as to whether or not the calculated angular velocity of the rotor and the estimated angular velocity of the rotor are substantially equal to each other. The calculated angular position of the rotor is changed by a predetermined phase value and is thereby corrected when it is determined that the calculated angular velocity of the rotor and the estimated angular velocity of the rotor are not substantially equal to each other.
