Apparatus and method for controlling motor driven power steering

A method for controlling an MDPS, comprising:

• filtering, by a filtering unit, a specific frequency from a first current steering angle provided from a steering angle sensor;
• removing, by a command steering angle control unit, noise of a first command steering angle inputted from an autonomous driving system, and outputting a second command steering angle;
• compensating for, by a steering angle position control unit, a first steering angle error corresponding to a difference between the second command steering angle and the first current steering angle filtered by the filtering unit, and outputting a first command current;
• compensating for, by a responsiveness improvement unit, a second steering angle error corresponding to the difference between the second command steering angle and a second current steering angle provided from a motor, and applying a compensation result value to the steering angle position control unit;
• and
• outputting, by the steering angle position control unit, a second command current by applying the compensation result value to the first command current.
