Problems solved by technology
[0003] The problem of cooperative control of structural vibration and attitude is not considered in the attitude control of the existing space station, which highlights the problem of "cooperative control" in the control of structural vibration and attitude. The design of the space station dynamics and control experiment platform is mainly used During orbital operation, the coupling between structural vibration and attitude control, design a corresponding cooperative control algorithm to slow down or eliminate its coupling, so that large spacecraft have higher control accuracy and reliability

A method for designing a space station dynamics and control experiment platform, comprising the following steps: step 1: design a space station structure model according to the layout structure diagram of China's future space station system; step 2: type selection; step 3: specific wiring and installation; the present invention Advantages: the present invention adopts the above-mentioned technical scheme, and has the following beneficial effects: in the field of cooperative control of spacecraft attitude and structural vibration, the key dynamics and control problems of large-scale spacecraft structural vibration and attitude cooperative control can be realized simply and with high precision, and the problem is solved. The design of the intelligent experimental platform avoids the lack of experimental verification of the large-scale spacecraft attitude control and structural vibration coupling problem in the prior art.
Description
technical field [0001] The invention relates to a design method of a space station dynamics and control experiment platform, which belongs to the field of mechanical structure mechanics and control. Background technique [0002] Space is a large spacecraft. Due to its large structural span and weak damping, it is easy to cause structural vibration during orbital operation, which affects the service life of the space station and the safety and reliability of attitude control. Therefore, the research on structural vibration and attitude control of the space station is of great importance. meaning. [0003] The problem of cooperative control of structural vibration and attitude is not considered in the attitude control of the existing space station, which highlights the problem of "cooperative control" in the control of structural vibration and attitude. The design of the space station dynamics and control experiment platform is mainly used During orbital operation, the coupli...
