摘 要：本文介紹了一種基于舵系統實測數據建立數學模型的方法，在工程應用中具有通用性、實用性。文中通過對舵系統工作原理分析與實測數據相結合的方式建立的數學模型。與實測曲線進行了對比，數學模型與實物具有較好的一致性。此方法可以應用于導彈舵系統論證與設計，與導彈制導控制系統進行迭代論證與設計。

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.
