<p>PURPOSE:To provide a motor controller in which the response of the motor electric current for the aimed electric current value is not delayed and the generation of the frictional feeling and vibration is suppressed, even in the application to a power steering device. CONSTITUTION:A control part 15 prepares the PWM instruction value for carrying out the pulse width modulation according to the aimed electric current value of the control quantity of a motor 2 and the motor electric current, etc., detected by an electric current detection part 13. A drive characteristic correction part 15c adds the correction quantity which is determined so that the relation between the PWM instruction value and the motor electric current becomes a nearly linear characteristic, to the PWM instruction value prepared by the control part 15a. A PWM driving part 12 consists of an H bridge circuit, etc., and is corrected by the drive characteristic correction part 15c, and further controls the electric current of the motor 2 by the PWM instruction value which is converted into pulses by a pulse generating part 15b.</p> |
