摘要
Abstract
Aimed at improving the disturbance rejection ability of the stable platform on the moving carrier,this paper proposes the stable control of disturbance observer with output observer by allowing for the mechanical resonant factors of stable platform servo system and describes the study of the loop structure,the input and output stability issues and the relationship between bandwidth and robustness of the disturbance observer.Simulation shows that LOS stabilization shows a precision of less than 0.04°,in the presence of the carrier moving at a maximum rate of 4（°）/s angular velocity in the case of sinusoidal signal movement with frequency of 5 Hz.Disturbance observer with output observer working,in the case of parameter perturbation,shows a better robust stability than feedback disturb observer.关键词
