Motor control system and power steering system

Abstract

One aspect of a noise compensation adjustment method includes: a measurement step of driving a motor to measure noise with respect to a coupled system including the motor and a driving body coupled to the motor and driven by the motor; an order identification step of, based on noise measured in the measurement step, identifying an order B of a component contributing to compensation of the noise from a k-th component and a 1/k-th component (k is an integer) in the rotation of the motor; an adjustment step of controlling driving of the motor using a component of the order B identified in the order identification step as a compensation value, and adjusting a component value of the order B to reduce the noise; and a recording step of recording the component value of the order B adjusted in the adjustment step as a compensation value for reducing the noise.
