The electronic control unit is configured to set a q-axis current value in response to a torque command value, and execute system loss reduction control for controlling a d-axis current value such that system loss, which is the sum of a copper loss, an iron loss and an inverter loss, is smaller than system loss at a time when motor loss, which is the sum of the copper loss and the iron loss, is a minimum. The copper loss, the iron loss and the inverter loss change as a current phase of a current vector changes in a q-d plane.

    摘要: A system including a motor loss reducing controller system utilizing input band-shifting, an integral control architecture and inverse band-shifting is disclosed. The motor loss reducing controller system may provide correction of harmonic currents flowing to a PM motor from a motor controller. The compensation is added to the PWM voltage command signals. Within a compensator, d-axis and q-axis current feedback signals are frequency shifted down by n times the fundamental frequency. This converts the initial motor stationary harmonic currents into DC values. The frequency shifting is completed by multiplying the feedback signal by sine and cosine carrier signals of the shifted frequency. An integral controller may cancel any component of error at a desired DC value. An inverse frequency-shift transformation is applied to the output of the I controller in order to shift the command output signal back to the original reference frame.

    摘要: In a control apparatus, an interference-reduction current calculator calculates, as an interference reduction current, a component of a current vector in a coordinate axis in a rotating coordinate system defined with respect to a rotor of the rotary machine. The current vector flows in the rotary machine, and the coordinate axis serves as an interference reduction coordinate axis in which the component of the current vector has reduced interference from change of the phase of the output voltage vector. An amplitude setter sets, as a manipulated variable for feedback controlling the interference reduction current to a command current value based on a command value for a controlled variable, one of: an amplitude of the output voltage vector, and an amplitude parameter indicative of a component of the output voltage vector. The component of the output voltage vector depends on the amplitude of the output voltage vector.

    摘要: A motor driving device of the present invention is a motor driving device that incorporates so-called vector control of controlling a current applied to a motor winding in accordance with the position of a rotor. The motor driving device receives the input of a duty command value from a host controller via a command input port, for example. The motor driving device obtains a current command or a speed command as a command value such that the input duty command value is equal to the duty of a drive pulse output from an inverter. Then, the motor driving device performs vector control based on the obtained command value.
