Problems solved by technology

However, the above methods are only applicable to celestial bodies with magnetic fields or ionospheres. For spaces without magnetic fields or ionospheres, chip satellites cannot achieve attitude maneuvering, which greatly limits the application range of chip satellites.

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] see figure 1 , a chip satellite based on electroactive polymers, including a chip satellite center platform 1, and the surroundings of the satellite center platform are respectively provided with left electroactive polymer tentacles 2, right electroactive polymer tentacles 3, and upper electroactive polymer antennas. Tentacle 4 and lower EAP antennae 5, left EAP antennae 2, right EAP antennae 3, upper EAP antennae 4 and lower EAP antennae 5 can bend to both sides .

[0023] In the first stage of the attitude maneuver of the chip satellite around the x-axis, such as figure 2 As shown, the left electroactive polymer antenna 2 on the left part of the chip satellite and the right electroactive polymer antenna 3 on the right part bend in the same direction with the same bending amplitude at the same time, thus causing the overall mass distribution of the chip sate...

Abstract

The invention discloses an electroactive polymer-based chip satellite and its attitude control method. According to the principle of conservation of angular momentum, the invention changes the overall mass distribution of the system through the deformation of the electroactive polymer arranged around the center platform of the chip satellite, thereby Realize the attitude maneuver of the chip satellite, so the attitude control method of the chip satellite proposed by the present invention gets rid of the dependence of the traditional chip satellite attitude control method on the magnetic field and the ionosphere, and the attitude maneuver of the chip satellite can be realized at any position in space, which greatly expands the The application scope of chip satellites; after the chip satellite attitude maneuver process is over, the chip satellite system is still kept in the plane state before the attitude maneuver. In this plane state, the antennae structure composed of electroactive polymer drivers is in a state that does not need to be powered , so that the chip star system can maintain the realized attitude maneuver without consuming any energy after the attitude maneuver.

Description

technical field [0001] The invention belongs to the field of aerospace, and in particular relates to a chip satellite based on an electroactive polymer and an attitude control method thereof. Background technique [0002] With the development of micro- and nano-technology, micro-satellites such as nano-satellites and pico-satellites have gradually become an important part of the space system, and have begun to transition from the stage of scientific exploration and technology experimentation to the stage of commercial operation. At the same time, the chip satellite concept proposed by the United States and Europe has attracted wide attention due to its advantages of low cost, rapid development and convenient launch. This chip satellite is realized by integrating units such as micro-electromechanical systems (MEMS), micro-opto-electromechanical systems (MOEMS) and complementary metal-oxide semiconductors (CMOS). Therefore, it is extremely small in size, extremely light in we...
