Design of High-Precision Cooperative Control System for Distributed Detector Platforms
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.
