| Abstract: | In this paper, the anti interference method for platform level loop is proposed, aiming at disturbances of platform level loop brought in by azimuth angular velocity when the platform rotated. LESO was applied to estimated and compensated disturbances in real time in level loop. The paper designed LESO based on the platform level loop model and simulate. The simulation results show that LESO can accurately estimate the disturbance and the dynamic compensation is effective Compared with the original system, platform level loop enhance the ability of restraining interference |
