<P>PROBLEM TO BE SOLVED: To provide a control device for an electric power steering device which cancels characteristics of respective phases of a motor and the control device to convert them to intended characteristics, improves ripple accuracy of torque and speed, etc. by making the characteristics of the respective phases correspond to each other, and prevents noise and uncomfortable steering feeling. <P>SOLUTION: A control device for an electric power steering device calculates a steering torque auxiliary command value based on steering torque generated in a steering shaft and vehicle speed; calculates a current command value of each phase from the steering torque auxiliary command value; and controls a motor applying steering auxiliary force to a steering mechanism based on a current control value calculated from the current command value of each phase and a current value of each phase of the motor. A filter having a characteristic to cancel characteristics of the respective phases of the motor and the control device is arranged in each route, to make the characteristics of the respective phases of the motor and the control device correspond to each other and convert the characteristics of the respective phases of the motor and the control device to intended characteristics. <P>COPYRIGHT: (C)2012,JPO&INPIT |
