Abstract：This paper introduces a method of building mathematical model based on measured data of rudder system， which is universal and practicable in engineering application. In this paper， the mathematical model of the rudder system is established by combining the working principle analysis and the measured data. Compared with the measured curve， the mathematical model is in good agreement with the physical model. This method can be applied to the missile rudder system demonstration and design， and can be used with missile guidance and control system for iterative demonstration and design.
