CONTROLLER FOR ELECTRIC POWER STEERING DEVICE

摘要

A control apparatus of an electric power steering apparatus is provided in which a nonlinear element of a motor model of the electric power steering apparatus is compensated beforehand to linearize the motor model and the back electromotive force of the motor is computed to compensate the back electromotive force for a control loop, and conduct back electromotive force compensation with no lag in order to realize a control apparatus of an electric power steering apparatus with less control error, stable controllability, small motor output torque ripple, good wheel steering feeling, and less motor noise.
