The Research of Parameter Identification in Servo System Model

This paper is mainly about the parameter identification of servo syste m in frequency domain. The modified Levy curve fitting method was used to identi fy the complex servo system based on testing magnitude and phase frequency chara cter, also the error for identification result was estimated. The result shows t hat this method is simple and valid, and satisfies the required precision in pra ctical application.
