PROBLEM TO BE SOLVED: To provide an excellent electric power steering apparatus in which a torque ripple caused by a quantization error in a current control system generated in a slow steering state or a steering holding state, namely, vibration and noise on a steering wheel, can be suppressed. SOLUTION: A smoothing filter is included in a current control system so that the quantization error is smoothed to suppress the torque ripple. COPYRIGHT: (C)2006,JPO&NCIPI |
