| Abstract(in English) | This paper shows the parameter estimation results using the measured displacement of the diaphragm by parameter estimation method for mirror filter based on quadratically constrained quadratic optimization. Mirror filter is a nonlinear compensator for reducing nonlinear distortions of electrodynamic loudspeakers and its coefficients are determined by the linear and nonlinear parameters of the loudspeaker. The parameter estimation method for mirror filter based on quadratically constrained quadratic optimization utilizes the displacement, velocity and acceleration of the diaphragm and the input voltage of the loudspeaker for parameter estimation. The effectiveness of the parameter estimation method have already been shown by a computer simulation. Hence, in this paper, the effectiveness of the parameter estimation method using measured displacement is discussed. |
