Satellite flight control closed loop simulation system based on component simulator

Abstract

The invention provides a satellite flight control closed loop simulation system based on a component simulator, which is applied to a system comprising a dynamics simulation server, a sensor simulator, an actuator simulator and a space-borne computer, wherein the formula of data output by the sensor simulator to the space-borne computer is the same as that of data output by a practical sensor to the space-borne computer, and the format of data received by the actuator simulator from the space-borne computer, i.e., the format of data input by an actuator is the same as that of data input by a practical actuator, so that the simulation reliability of the satellite flight control closed loop simulation system can be enhanced effectively; the component simulator is adopted instead of a real physical device, so that the simulation system has the advantages of low cost and low complexity; and meanwhile, the simulation system has the characteristics of high generality, high flexibility and high automatic degree, so that the research period of a satellite can be shortened effectively, and the research cost of the satellite is reduced.

Description

technical field [0001] The invention belongs to the technical field of satellite simulation testing, in particular to a satellite flight control closed-loop simulation system based on component simulators. Background technique [0002] In the field of aerospace engineering, due to the high cost of satellite development and the complex and harsh operating environment of satellites, it is generally necessary to simulate the flight control system of the satellite to verify the correctness of the design of the flight control system of the satellite. And test the function and performance of the satellite's flight control system. [0003] Usually, the flight control simulation system of the satellite can adopt semi-physical simulation and full-physical simulation. Among them, in the all-physical simulation system, since various real physical devices are directly connected to the simulation loop, the influence of these real physical devices on the performance of the simulation con...
