摘要：
PROBLEM TO BE SOLVED: To obtain an electric power steering control device with improved steering feeling corresponding to steering speed.
SOLUTION: This electric power steering control device includes: a steering torque detector for detecting steering torque; a steering speed detecting part for detecting steering speed; a compensation calculation part for outputting a current command by performing calculation of a transfer function having at least a low frequency pole being a pole and at least two intermediate zero points being zero points with respect to the steering torque detected by the steering torque detector; a transfer function changing part for changing the characteristics of the low region pole or the two intermediate zero points according to the steering speed; and a current control part for controlling a motor so that the current of the motor matches the current command.
