摘要： A control device that controls an electric motor drive device. The control device is configured with a first voltage control section that derives a modulation rate representing a ratio of an effective value of the voltage command values to the DC voltage and a voltage command phase. A second voltage control section generates a control signal for controlling the DC/AC conversion section on the basis of the modulation rate, the voltage command phase, and a magnetic pole position representing a rotational angle of a rotator of the AC electric motor. A computation cycle of the first voltage control section is set to be longer than a computation cycle of the second voltage control section.

摘要： A motor control device that has a high-frequency component, and a DC bias component that has a magnitude which causes a motor to be magnetically saturated and take on a certain value over a predetermined period, and is positively and negatively symmetrical are impressed as an observation command on a d-axis current command. The polarity of the magnetic pole of a permanent magnet is identified based on a relationship of large and small magnitudes between a first amplitude, which is attained during a period during which a DC bias component takes on a positive certain value, among amplitudes of a high- frequency component contained in a d-axis response voltage computed based on a feedback current respondent to the observation command, and a second amplitude attained during a period during which the DC bias component takes on a negative certain value.

摘要： In switching between asynchronous PWM control and synchronous PWM control, control can be simplified. An apparatus has a first pulse pattern generation processing module which generates a synchronous PWM signal in a first pulse pattern formed of multiple pulses defined in accordance with two or more parameters based on a voltage command value, and a second pulse pattern generation processing module which generates a synchronous PWM signal in a second pulse pattern formed of a single pulse. The first pulse pattern generation processing module modifies the individual parameters in switching pulse patterns between the first pulse pattern and the second pulse pattern. The individual parameters are modified to move the pulse patterns, and thus control can be simplified.

摘要： A general-purpose comparator can be used as a comparison processing module to reduce the costs of a motor drive control apparatus. The apparatus has an electric machine; a magnetic pole position computation processing module; a pattern generation processing module; a switching angle computation processing module which computes a switching angle where switching is done in a next control period based on a pulse pattern; a comparison processing module which compares the magnetic pole position with the computed switching angle to generate a comparison signal; and an on-off output processing module which generates a PWM signal based on the comparison signal indicative of the comparison result. In this case, because the magnetic pole position is compared with the computed switching angle to generate the PWM signal based on the comparison signal, a general-purpose comparator can be used as the comparison processing module.
