| Abstract: | The composing and controlling diagram block of the optoelectronic tracking system were analyzed,and every part of velocity stabilization loop was modeled.Through the open-loop frequency characteristic test of the gimbal,the actual frequency characteristic curve of the tracking system was plotted.By using total least square algorithm on testing data to approach curve,the mathematics model of the controlled object was built.Comparing with the actual frequency characteristic curve,the model has made good coherence. |
