Multidisciplinary simulation of space-based telescope using HLA

Simulation is an effective method to analyze the control system performance of a space-based telescope which is described by a coupling multidisciplinary model, involving mechanics, optics, controls and electronics. Based on many preview researches on simulation of space optical systems, High Level Architecture (HLA) simulation technique is considered to establish the simulation federation in this paper, which is fitter for multi-team research environment. According to HLA rules, the distributed simulation federation scheme including four disciplinary federates and two management federates is designed to simulate the wave-front error correction procedure. Meanwhile, HLA object model template design method, the large scale data transmission and the time management technology are respectively discussed for the simulation application. The simulation result proves that the control method is correct, as well as that the HLA-based simulation scheme can be well applied in the area of multidisciplinary simulation of space-based telescopes.
