Abstract :
An add-on nonlinear feedback controller is proposed to work together with the existing linear controller to deal with external disturbance. The implementation of the proposed scheme is very simple, may be even simpler than the linear controller. Chassis tests on several notebook PC models showed that the proposed method is effective to handle wide band vibration.
