Abstract
To alleviate the impact of micro-vibrations on the pointing accuracy and imaging quality of large-scale space optical payloads,a lightweight,four-legged integrated platform for vibration isolation and pointing was designed.This platform,equipped with pitch and yaw adjustment functions,utilized voice coil motors to achieve both vibration isolation and precise pointing.Firstly,a simplified dynamic model of the platform was established.Dynamic control equations were then derived based on the PID control strategy,and the effects of centroid shift and control parameters on control performance were analyzed.Subsequently,a loaded integrated vibration isolation and pointing platform was designed.An active control simulation model was constructed using ADAMS rigid-flexible coupling and MATLAB/Simulink control joint simulation technology.Simulation results indicated that the platform could achieve a vibration attenuation effect of 41 dB at the resonance peak,with good suppression capabilities at frequencies below the resonance peak.Additionally,the circular tracking pointing error was only 2.19%.The platform confirmed its good vibration isolation and pointing capabilities.This research has theoretical guiding significance for the manufacturing of actual physical prototypes.关键词
