摘　　要：从航空光电系统瞄准线惯性稳定的内涵和应用需求入手,以典型惯性稳定平台控制系统为例,围绕伺服元件/电路噪声、结构特性和动态环境三个方面,归纳总结了影响惯性稳定性能的主要因素.着重分析了控制回路特性参数、控制器以及结构特性对瞄准线惯性稳定性能的影响,指导惯性稳定平台结构与控制系统设计.为满足航空光电系统远程探测的需求,克服内部光学元件相对位移或变形引起的瞄准线抖动,在惯性稳定平台基础上引入基于参考光的高精度瞄准线惯性稳定技术,并开展了相关分析与实验工作,最后对瞄准线惯性稳定技术的发展提出了几点建议.The control system of a typical inertial stable platform is taken as an example to analyze the connotation and application requirements of line-of-sight inertial stability of airborne optoelectronic systems.The main factors affecting the performance of inertial stability are summarized based on three aspects—servo component/circuit noise,structural characteristics,and dynamic environment.The influence of control loop characteristic parameters,controller characteristics,and structural characteristics on line-of-sight inertial stability is thoroughly examined to guide the design of an inertial stable platform structure and control system.To meet the requirements for long-distance detection in aeronautical optoelectronic systems and overcome the line-of-sight jitter caused by relative displacement or deformation of internal optical components,a high-precision line-of-sight inertial stabilization technology based on reference light was introduced on the basis of the inertial stabilization platform,and relevant analyses and experiments were carried out.Finally,directions have been provided for the future development of high-precision inertial stabilization technology.
