摘要： A method for reducing audible motor noise in a motor drive, wherein the motor drive includes a motor controller driving a PWM space vector modulator providing gating pulses to an inverter providing phase currents to the phase windings of the motor, and wherein phase currents of the motor are determined by taking samples of the DC link current in a DC link powering the inverter. The method comprises determining the speed of the motor and comparing the speed to a preset threshold, the preset threshold defining a speed at which audible noise is generated by the motor due to a minimum pulse constraint being imposed on the motor phase currents in order to reliably sample the DC link current to measure the phase current. If the speed is below the threshold, the DC link current in the DC link is sampled using a reduced number of current samples for a PWM cycle of the PWM space vector modulator to reduce audible motor noise.

摘要： In order to simultaneously realize an improvement in disturbance suppression force of an electric motor control apparatus and vibration suppression of a load machine, a velocity control circuit receives a velocity command signal as a target value of velocity of an electric motor and a corrected velocity signal, obtained by correcting a velocity signal with a velocity correction signal, and outputs a torque command signal specifying target torque of the electric motor driving the load machine. A vibration suppression circuit outputs a velocity correction signal, based on an acceleration signal, indicating acceleration of the load machine. A transfer function from the acceleration signal to the torque command signal is obtained by multiplying a transfer function from a position signal, indicating position of the electric motor to the torque command signal, by a proportion characteristic having a specified gain and integration characteristic.

摘要： The present invention provides a control apparatus of a electric power steering apparatus which can suppress a vibration and a noise of a motor caused by a torque ripple which is generated at a tie of applying a field-weakening control to the motor or on the basis of a motor circulating current. Accordingly, the control apparatus actually measures a relation between a basic correcting current and a rotor position which can suppress the torque ripple generated at a time of applying the field-weakening control or the torque ripple based on the motor circulating current, previously, and adds a correcting current which is regulated by taking into consideration a magnitude of a weak field current of a correcting current, a magnitude of an angular velocity of the rotor or an electrical angle of the circulating current with respect to the basic correcting current, to an original current command value.

摘要： Presented is a harmonic regulator that regulates a plurality of individual harmonics in a system having periodic torque disturbances to commanded values, including zero. For each harmonic being regulated, a feedback signal having at least one harmonic component due to the harmonic being regulated is transformed from a source reference frame to a harmonic reference frame of the harmonic being regulated to form a qd feedback signal. The qd feedback signal is subtracted from the commanded value to form a qd signal and regulated. The regulated qd signal is transformed to a destination reference frame to form a compensation signal and the compensation signal is added to a control signal to form a qd control signal that drives each harmonic being regulated towards the commanded value.
