Frequency Domain Analysis Based Nonlinear Feedback Control for Suppressing Periodic Disturbance

Based on the output frequency response function of nonlinear systems, a novel approach to the design of a nonlinear feedback control for periodic disturbance suppression is proposed. A general design procedure for the nonlinear feedback controllers is given and demonstrated by the design of an active vibration control system. Theoretical analysis and simulation results verify the effectiveness of the new approach
