针对导引头三框架随动系统，根据其典型工作特点，建立了随动系统机械、控制元件、控制回路数学模型，并分析了影响随动系统性能的误差因素。按照模块化设计思想，形成了通用的、参数可调的随动系统数字样机，并开展了基于ADAMS和MATLAB环境的动力学和控制过程联合仿真。分析结果表明，随动系统数字样机能够实现物理样机的功能和性能，有效响应参数的变化，可为导引头随动系统指标论证分析、方案优化设计提供有效手段，未来将得到越来越普遍的应用。

The mathematical models of mechanism, control elements and control loop are presented for the three-ax-is servo system of a seeker based on its typical working characteristics, and the error factors influencing the per-formance of the servo system are analysed.Universal and parameterized digital prototype of the servo system is es-tablished based on modularization, and associated simulation of mechanism and control based on ADAMS and MATLAB is given.Simulation result shows that the actual prototypeˊs function and performance can be achieved on the digital prototype and the change of parameters can be responded effectively.Therefore, the digital prototype can be an effective approach for demonstrating, analysing and desiging the servo system, and it may be applied perva-sively in future.
