APPARATUS AND METHOD FOR CONTROLLING MOTOR DRIVEN POWER STEERING

An apparatus for controlling an MDPS may include: a filtering unit (400) configured to filter a specific frequency from a first current steering angle provided from a steering angle sensor; a command steering angle control unit (100) configured to remove noise of a first command steering angle inputted from an autonomous driving system (20), and output a second command steering angle; a steering angle position control unit (200) configured to compensate for a first steering angle error corresponding to the difference between the second command steering angle and the first current steering angle filtered by the filtering unit (400), and output a first command current; and a responsiveness improvement unit (300) configured to compensate for 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 apply the compensation result value to the steering angle position control unit (200).
