摘要： A control device includes angular velocity detecting circuitry, feedback circuitry, torque command calculation circuitry, a limiter, a drive controller, and correction circuitry. The angular velocity detecting circuitry detects an angular velocity of a motor. The feedback circuitry obtains a feedback value from the angular velocity. The torque command calculation circuitry obtains a torque command value according to a superordinate torque command value supplied from a superordinate device and the feedback value. The limiter limits the torque command value obtained by the torque command calculation circuitry so as not to exceed a preset torque upper limit value. The drive controller performs a drive control of the motor according to the limited torque command value. The correction circuitry corrects the superordinate torque command value or the torque command value according to the feedback value and the superordinate torque command value.

摘要： A technique for reducing an operation noise even when a high-pass filter is used for controlling a motor is provided. A controller is used in a motor control system for driving a motor by using a drive circuit and an inverter. The controller includes a current control block. The controller performs feedforward control by using a current value, compensates for a term of a self-inductance of the motor included in a current control block by an inverse model, compensates for a phase characteristic of a transfer function of the inverse model by an advance component, and corrects a gain characteristic of the transfer function of the inverse model by a function of a physical quantity obtained based on an angular velocity of the motor, thereby compensating for a phase delay and a gain reduction of a torque output generated by the self-inductance.

摘要： A motor control system includes an inverter, and a control calculation unit that feedback-controls the inverter. The control calculation unit includes a voltage control calculation unit that calculates a voltage command value indicating a voltage to be applied to the motor from the inverter on the basis of a current deviation between a current command value and an actual current detection value, a torque ripple compensation calculation unit that adds a compensation value for compensating a torque ripple in the motor to a signal value on at least one of an upstream side and a downstream side in a signal flow that passes through the voltage control calculation unit, and a current limit calculation unit that limits the current command value by adaptive control based on an actual angular velocity value indicating an angular velocity at which the motor rotates.
