A semi-physical simulation test system for sun-oriented control

Abstract

A semi-physical simulation test system for sun-oriented control, including a spaceborne computer system, a gyroscope, an infrared horizon, a star sensor, a three-axis magnetometer, an actuator and a target simulator, the target simulator simulating a space environment , the motion simulator simulates the attitude motion of the aircraft, and the on-board computer system calculates the attitude and control amount according to the measurement data obtained by each measurement stand-alone, and outputs it to the actuator, and also includes the sun sensor equivalent Device, dynamic geomagnetic field simulator, target simulator, motion simulator, PXI acquisition control computer, dynamics simulator, data distribution unit, telemetry and remote injection machine, database, display terminal, CAN bus network and optical fiber reflective memory network. The invention solves the problem in the prior art that the ground simulation verification of sun orientation control cannot be carried out under the condition that the attitude of the aircraft rolls abnormally, and has the beneficial effect of improving the authenticity and effectiveness of the test.

Description

technical field [0001] The invention belongs to the technical field of ground simulation test and test of an aircraft attitude and orbit control system, in particular to a semi-physical simulation test system for sun-oriented control. Background technique [0002] The launch of the aircraft's solar panels into orbit and capture of the sun, as well as the long-term sun-oriented control of the aircraft's solar panels, are the fundamental guarantees for ensuring the energy supply required for the aircraft's orbit and the realization of its mission. Especially when the attitude of the aircraft is abnormal and the solar panels cannot be oriented to the sun normally, if it cannot be oriented to the sun for a long time, the flight cannot complete the scheduled on-orbit mission due to insufficient energy, or even the end of the life of the aircraft. Therefore, usually the aircraft attitude and orbit control system will design a corresponding emergency plan for the abnormal attitude ...

AI Technical Summary

Problems solved by technology

This kind of simulation method has the best simulation accuracy and effectiveness, but the simulation environment is complicated to build, expensive, requires professional operators to operate the equipment, and is limited by the power supply and gas supply on the air flotation platform, so it cannot carry out simulation verification for a long time

At the same time, a lot of preparatory work is required before each test, which is not convenient for the test to be carried out.

Especially limited by the movement range and speed of the air bearing table, it is impossible to carry out the ground simulation verification of the directional control of the sun when the aircraft attitude is abnormal and rolls.
