Agent-based solar sail distributed simulation system

Abstract

An Agent-based solar sail distributed simulation system comprises an orbit recursive model unit, an earth shadow model unit, a thermal control system model unit, a power supply system model unit, an attitude control model unit and an orbit control model unit, each model unit is an independent Agent module, and interconnection and data interaction between the Agent modules are achieved through the TCP / IP protocol. According to the system, microscopic behaviors of each component system, namely on-orbit status of each subsystem of a solar sail, can be described, the Agent modules can also be combined to describe macroscopic characteristics of the solar sail, so that each component unit and the integral body of the solar sail can be fully simulated conveniently, and the problems in the design stage of the solar sail can be found timely. In addition, distributed design is adopted by the system, complexity can be reduced, and simulation efficiency of the system can be largely improved.

Description

technical field [0001] The invention belongs to the technical field of simulation testing and relates to a solar sail distributed simulation system. Background technique [0002] With the rapid development of technology, solar sails, as a new type of spacecraft, gradually come into people's sight. A solar sail generally refers to a spacecraft that uses the light pressure of sunlight for space navigation. The modeling and simulation of the solar sail system can help analyze the characteristics of the solar sail system, optimize the design of the solar sail, and then promote the development of the solar sail. [0003] The current simulation technology mainly includes physical simulation, mathematical simulation and semi-physical simulation.

AI Technical Summary

Problems solved by technology

[0004] Physical simulation usually requires the model to have the same physical properties as the prototype. This simulation can reflect the characteristics of the original system in a more realistic and comprehensive manner, but the production of the model is very complicated and the cost is high.

Physical simulation cannot meet the simulation requirements of solar sail system

First, the production cost of the simulation model is very high; second, the physical simulation cannot obtain the real working environment of the solar sail

Similarly, semi-physical simulation also includes a certain real model, so there will be a problem of high cost, and it cannot be widely used by solar sail simulation systems

[0005] Computer-based mathematical simulation addresses high cost of physical simulation

However, traditional mathematical simulation is based on the establishment of the model of the entire system, which is difficult to describe complex systems such as solar sail spacecraft

It is mainly reflected in three aspects: 1) Traditional mathematical simulation is difficult to display the behavior of subsystems that constitute a complex system, and it is difficult to analyze the working status of each subsystem of a complex system and the data interaction between subsystems; 2) Traditional mathematical simulation Process-oriented modeling technology is mostly used, which is not real-time; 3) When simulating complex systems with traditional mathematical simulation, the simulation efficiency is generally low
