Space station solar wing capable of correcting speed and speed correcting method thereof

Abstract

The invention discloses a space station solar wing capable of correcting speed and a speed correcting method thereof, two rotary transformers are used for solar wing speed control, and the two rotarytransformers are respectively a high-speed end rotary transformer and a low-speed end rotary transformer,wherein the high-speed end rotary transformer is used for speed control under a normal workingcondition, and the low-speed end rotary transformer is used for high-speed end speed correction when solar wing position tracking has deviation under an interference condition. The two rotary transformers cooperate together to complete high-precision speed tracking of the solar wing of the space station. According to the invention, high-precision speed tracking of the sun orientation by the solarwing of the space station experiment module can be realized, and the position tracking requirement of the solar wing is met, so that the solar wing can obtain the maximum energy capture conversion efficiency.

technical field [0001] The invention relates to the solar wing control technology in the space field, in particular to a space station solar wing capable of speed correction and a speed correction method thereof. Background technique [0002] The space station is a large-scale space science project. The solar wing of the space station, especially the two experimental module solar wings, has a single wing span of about 30m and has the characteristics of large size, large inertia, and large flexibility. At the same time, due to the characteristics of the space station's solar wing control mode, complex control process, many interference factors, and long transmission chain, it is different from the previous spacecraft solar wing control, and the space station's solar wing speed control has many influencing factors.

Problems solved by technology

At the same time, due to the characteristics of the space station's solar wing control modes, complex control process, many interference factors, and long transmission chains, it is different from the previous spacecraft solar wing control, and the space station's solar wing speed control has many influencing factors.

The speed control of the solar wing of the space station requires high tracking accuracy. Speed ​​fluctuations will cause deviations in the position tracking of the solar wing. The position tracking deviation of the solar wing will make the solar wing of the space station unable to face the sun with the maximum receiving surface, resulting in the capture of solar energy by the solar wing. Reduced conversion efficiency

Therefore, for the speed control of the solar wing of the space station experiment module, the previous spacecraft solar wing speed control technology based on a single rotary transformer can no longer meet the current control requirements.
