Abstract

Researchers present a method of reducing nonlinear distortion in loudspeakers to a greater extent than by classical feedback-control methods without using the information of nonlinear parameters of the plant loudspeaker. To achieve this, we adopt a modern control theory called model-following control and the optimal feedback gain is determined uniquely by using this control method. The results of a computer simulation show that we can obtain a greater control effect by using our proposed method than by classical feedback control. The robustness of the proposed method is also verified.
