A Space Station Solar Wing Capable of Velocity Correction and Its Velocity Correction Method

Abstract

The invention discloses a space station solar wing capable of speed correction and a speed correction method thereof. Two rotary transformers are used for speed control of the solar wing, which are respectively a high-speed end rotary transformer and a low-speed end rotary transformer. Among them, the high-speed side resolver is used for speed control under normal working conditions, and the low-speed side resolver is used for the high-speed side speed correction when there is a deviation in the position tracking of the solar wing under interference conditions. The two resolvers work together to complete the high-precision speed tracking of the solar wing of the space station. The invention can realize the high-precision tracking of the sun-oriented speed of the solar wing of the space station experimental cabin, and meet the requirements of the position tracking of the solar wing, 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. 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...

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.
