ABSTRACT:
A steering-torque detecting unit detects a steering torque applied by a driver as a steering torque signal. A phase-lag compensation unit performs an operation having a frequency response characteristic of multiplying a phase-lag compensation by a constant for the steering torque signal based on a signal obtained by applying an amplification by a first gain and a low pass filter on the steering torque signal and a signal obtained by applying an amplification by a second gain on the steering torque signal. A current control unit controls a current applied to a motor to follow a current command that is obtained based on an output of the phase-lag compensation unit.
