Embodiment Construction

[0024] Specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The sailboard of the satellite is the main means for the satellite to obtain energy in orbit. Generally, the single-degree-of-freedom sailboard is in the state of three-axis stability of the satellite's orientation to the ground, and the rotation direction is perpendicular to the orbital plane. In this way, in a sun-synchronous orbit (the orbital characteristics determine that the angle between the sun and the orbital plane varies within a small range), when the sun moves near the orbital plane, turning the sailboard can ensure that the sun shines directly on the sailboard. In a non-sun-synchronous orbit, the angle between the sun and the orbital plane varies greatly (-90 degrees to 90 degrees), and the sun may be parallel to the sailboard. In this case, the sailboard cannot obtain energy. As we all know, to rotate a vector to ...

Abstract

The invention discloses a non-sun-synchronous orbit satellite double-shaft sailboard control method. A double-shaft sailboard is a solar sailboard structure which has two rotational degrees of freedom and of which the two rotating shafts can independently control work. The double-shaft sailboard control method comprises a control method of each single-shaft sailboard in the double-shaft sailboard and an implementation method during double-shaft cooperative work of the sailboard. In the single-shaft control method of the sailboard, measurement modes and rotation strategies for the sailboard indifferent work modes of the satellite are mainly designed. In the double-shaft cooperative work method, the working order of each single shaft and the rotation logic are specified. The inconvenience that a non-sun-synchronous orbit satellite needs to frequently perform attitude maneuver to ensure the sailboard tracks the sun is solved by applying the double-shaft sailboard control method on a satellite. By the method, the satellite can track the sun in real time on orbit by controlling the rotation of the sailboard, so that the energy supply on the satellite is guaranteed, and the requirement of the satellite over the ground directional triaxial stability is met.

Description

technical field [0001] The invention relates to a method for controlling a two-axis sailboard of a satellite in a non-sun-synchronous orbit, which can realize two-degree-of-freedom motion of the sailboard on the satellite, and is mainly used on satellites in a non-sun-synchronous orbit. Background technique [0002] Solar cells are laid on the satellite sailboard, and the stretched sailboard can greatly increase the area where the satellite can obtain solar energy. Therefore, the sailboard is an essential equipment for most satellites to obtain solar energy, and it is also the main energy source for satellites flying in orbit. At present, in addition to the use of fixed-wing sailboards (fixed-wing sailboards mean that the sailboards are fixed to the star and cannot rotate), the satellites in orbit in my country use single-degree-of-freedom sailboards. The single-degree-of-freedom sailboard is equipped with a sailboard drive mechanism (a kind of rotating motor), whose functio...
