Abstract :
When the dynamic type speaker is driven, the problem of wavy reproducibility by existence and the phase rotation of the transition distortion of the speaker is caused in the electromagnetic braking method used in general. In this research, the application of the sliding mode control which is one of the nonlinear controls is applied to the drive of the speaker. The band is divided in this paper, and the preview sliding mode control is used. And it makes the control possible in a wide band.
