Description

technical field [0001] The invention relates to an active control test platform and method for simulating intelligent flexible space sailboard structure vibration, in particular to a piezoelectric intelligent material flexible board structure vibration active control test platform and method based on DSP measurement and control core. Background technique [0002] The solar panels of aerospace vehicles usually exist in the space environment in the form of large cantilever beam structures, and have the characteristics of low stiffness, small damping, low natural frequency and dense low-order modes. Due to the harsh space environment, the influence of cosmic wind, particle flow, and the maneuvering of the spacecraft itself, it is very easy to cause continuous vibration of the solar panel structure of the spacecraft. If effective anti-vibration measures are not taken, its large-scale vibration response will last for a long time, which will not only affect the working performance...
