Problems solved by technology

However, if the wireless network is used to transmit attitude information, problems such as network delay will inevitably occur, which will affect the control accuracy; and the intelligent flywheels are independent of each other, how to coordinate and complete the task instructions is also a key issue that needs to be considered

Embodiment Construction

[0047] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0048] The distributed intelligent flywheel system includes three sets of orthogonally installed intelligent flywheels and one set of obliquely installed intelligent flywheels. Each intelligent flywheel includes a motor and flywheel module, a processor module, a memory module and a wireless transmission module, all of which have the ability to independently calculate and control output .

[0049] A spacecraft attitude control method based on distributed intelligent flywheels of the present invention consists of three sets of orthogonally installed intelligent flywheels and a set of obliquely mounted redundant intelligent flywheels to form an attitude control actuator, and the control method includes fault self-checking of each intelligent flywheel , receiving the attitude information broadcasted by the sensor system, synchronous estimation of ...

Abstract

The invention discloses a spacecraft attitude control method based on distributed intelligent flywheels. According to the method, a plurality of intelligent flywheels form a distributed attitude control system through wireless networking; a distributed control method is provided according to characteristics of the system; a strategy comprises the steps of fault self-inspection, working intelligentflywheel combination determination, sensor system broadcast attitude information reception, time delay state synchronization, independent solution control output and the like. Therefore, distributedcooperative computing of the spacecraft attitude control system is realized, modular assembly of a spacecraft platform is facilitated, and the method has great significance in rapid assembly testing of spacecrafts and plug-and-play effects of satellite-borne components.

Description

technical field [0001] The invention relates to the technical field of spacecraft attitude control, and more particularly, to a spacecraft attitude control method based on a distributed intelligent flywheel. Background technique [0002] In recent years, with the continuous development of aerospace technology, the design and manufacture of spacecraft tend to be more and more miniaturized in mass and volume. For micro-nano satellites that use traditional interfaces and cables to transmit information between subsystems and components, The weight of interfaces and cables can account for 8% to 10% of the weight of the entire satellite; at the same time, because the satellite test adopts the serial test method, when a new component is connected to the satellite system and needs to be tested for function, it needs to be disconnected. Electrical processing, which will affect the testing work of other equipment, is not conducive to the rapid assembly and production of micro-nano sat...
