Micro-nano satellite attitude and orbit control semi-physical simulation comprehensive experimental platform

Abstract

The invention discloses a micro-nano satellite attitude and orbit control semi-physical simulation comprehensive experimental platform which comprises a host machine, a target machine, an environmentsimulation computer, an attitude and orbit control computer, an execution mechanism and I / O hardware equipment of an acquisition card. The host machine is connected with the target machine by an Ethernet; the target machine is in communication connection with the environment simulation computer; the environment simulation computer is used for simulating a space environment where a satellite is positioned and obtaining actual information data of an attitude and an orbit of the satellite by a measurement module; simulated information data of the attitude and the orbit of the satellite is compared to the actual information data of the attitude and the orbit of the satellite in the environment simulation computer to obtain an error amount; the environment simulation computer is in communication connection with the attitude and orbit control computer; and the attitude and orbit control computer calculates a control quantity and sends out a control instruction to the execution mechanism. Themicro-nano satellite attitude and orbit control semi-physical simulation comprehensive experimental platform has the advantages of high operational capability, high accuracy, closer simulation operation principle and result to the actual working condition of the satellite, high real-time performance and low cost.

Description

technical field [0001] The invention belongs to the technical field of micro-nano satellites, and in particular relates to a semi-physical simulation comprehensive experiment platform for attitude and orbit control of micro-nano satellites. Background technique [0002] Due to the operation and work in a special environment, the ground verification test of the spacecraft is an inevitable link. Space vehicle ground simulation can be divided into pure numerical simulation, semi-physical simulation and full physical test experiment. Pure numerical simulation refers to a simulation method that uses the mathematical model of the simulated object, does not require hardware support, and only simulates numerically through a computer system. The advantage of this method is that it is not affected by hardware conditions, low cost, and easy to implement. It is a commonly used verification method in the research and development stage. Therefore, it is difficult to effectively evaluate...
