Abstract

The invention discloses a solar wing speed stability control system and method based on a multi-filter structure. The solar wing speed stability control system comprises a judgment module, a first switching module, a Butterworth low-pass filter, a second switching module, a structural filter, a third switching module and an interference suppression filter, wherein an input end of the first switching module is connected with an output end of the judgment module; an input end of the Butterworth low-pass filter is connected with a first output end of the first switching module; a first input endof the second switching module is connected with an output end of the Butterworth low-pass filter; a second input end of the second switching module is connected with a second output end of the firstswitching module; an input end of the structural filter is connected with a first output end of the second switching module; a first input end of the third switching module is connected with an outputend of the structural filter; a second input end of the third switching module is connected with a second output end of the second switching module; an input end of the interference suppression filter is connected with a second output end of the third switching module. According to the solar wing speed stability control system and method based on the multi-filter structure, problems of low stability control accuracy of a single filter on a speed of a solar wing and poor stability of the single filter are solved, and in a mode of combining various filters to carry out filtering, stability control on the speed of the solar wing is ensured.

Description

technical field [0001] The invention relates to the technical field of space station solar wings, in particular to a solar wing speed stabilization control system and method based on a multi-filter structure. Background technique [0002] The solar wing of the space station experiment cabin is the largest, largest and heaviest solar wing with large flexibility characteristics developed by our country so far. The single wing has a wingspan of about 30m and an inertia of about 3.4e5Kgm2. Features such as great flexibility. [0003] Since the complex interference of the space environment will cause the flexible vibration of the solar wing, it is impossible to realize the high-precision speed stability control of the solar wing. Therefore, it is necessary to effectively suppress the interference of the solar wing to avoid excessive flexural vibration of the solar wing. However, due to the nonlinearity, low fundamental frequency, and dense modes of large-area solar wings, it is ...
