基于几何模型的光学共相控制系统指标分解方法
Decomposition method for optical co-phase control system metrics based on geometric models
摘要
Abstract
Distributed optical interferometric detection systems involve multi-level actuators,making it dif-ficult to effectively connect the specifications of different subsystems.To address this problem,this paper proposed a specification decomposition method for optical co-phase control systems based on a geometric model.Based on the geometric characteristics of optical propagation,an optical-path vector model was es-tablished for a distributed detector configuration consisting of one combiner and two collectors.The error-transfer chain of the multi-level control system composed of the satellite platform and payload,as well as the mapping relationship between subsystem specifications,was then analyzed.According to the range of satellite-platform pose control errors in engineering applications,static specification decomposition and sen-sitivity analysis were carried out for the error-transfer process.The closed-loop control objectives of the payload actuators were further quantitatively analyzed and numerically simulated based on the decomposed specifications.Simulation results show that,under the conditions of satellite-platform position error≤5 cm,attitude error≤5 arcsec,translational velocity≤1 mm/s,and angular velocity≤1 arcsec/s,the multi-level hierarchical control scheme constructed according to the proposed specification decomposition results can achieve stable convergence of co-phase errors.The final pointing and OPD control accuracies reach the levels of 0.01 arcsec and 10 nm,respectively,satisfying the requirements of optical interferome-try.This method provides an analysis approach and design reference for control hierarchy division,control-object selection,and specification allocation in similar distributed detection systems.关键词
