摘要
面向分布式空间光干涉高精度探测需求,针对分布式探测器平台协同指向中存在的内外干扰难以克服的问题,提出一种协同控制系统设计方案.首先进行分布式探测器动力学建模与干扰机理分析;其次设计分布式干扰观测器及RBF网络干扰学习观测器,将扰动参量与系统其他状态量进行解析与分离,以降低参量不确定性对系统稳定性的影响;最后设计姿态跟踪控制器,以消除系统不确定扰动.仿真结果表明设计方案的有效性,为分布式探测器平台协同控制系统设计提供了新思路.
Abstract
Aiming at the demand of high-precision detection for the distributed spatial optical interference,a cooperative control system design scheme is proposed in this paper to address the problem of insurmountable internal and external interferences in the cooperative pointing of distributed detector platforms.Firstly,dy-namics modeling of the distributed detectors and analysis of the interference mechanism are implemented.Then,on the basis of that,a distributed interference observer and an RBF network interference learning ob-server are designed for analyzing and separating the perturbation variables from other state quantities of the system,which are used to reduce the influence of perturbation uncertainties on the system stability.Further-more,an attitude tracking controller is designed to eliminate uncertain perturbations of the system.Finally,simulation results show the effectiveness of the proposed design scheme and inspire the design of cooperative control system for distributed detector platforms.
