摘要
在基于扫描反射镜的惯性稳像工作原理分析的基础上,讨论了几种惯性稳像构型的结构形式和特点。针对具有惯性稳定轮的传动式稳像构型,推导了稳像回路的数学模型,设计了稳像控制算法,并且利用Matlab仿真对稳像控制算法进行了验证;最后,设计了稳像精度测试方案并进行了稳定精度测试。测试结果表明,该稳像系统对扰动抑制能力较高,能满足实际应用要求。
Based on analysis of inertial line-of-sight(LOS) stabilization principle using scan mirror, the characteristics and merits of inertial image stabilization configuration are discussed.The mathematical model of stabilization servo loop based on mechanical driver and inertial balancer is deduced and stabilization control algorithm is proposed.The Matlab simulation results verify the validity of the algorithm.The stabilization accuracy testing method is proposed and testing experiment on specially designed workbench is implemented.The testing results indicate that capability of disturbance rejection is pretty better and inertial image stabilization control system can satisfy the airborne application requirement.
