Combing with optimum parameters  -- filter based on high sampling rate was established  the effect of and sample rate on filter nature frequency were evaluated. According to the requirements of stabilization platform  the principle of steady and transient tracking filter differential were proved. With the hypothesis of constant acceleration  the frequency characteristics of angular velocity transfer function were analyzed  three-dimensional Kalman filter was simplified  and the filter parameters were designed. The results show that when the spectrum of input signal was lower than 6rad/s  parameters was 0.02  and sampling period were 0.08ms and 0.1ms respectively  the filter can realize differential exactly  when the spectrum was 9rad/s  the precision was no less than 1.1%  the phase leading of angular position was no less than 70  the natural frequency should be higher than the cut-off frequency of stabilization platform was two or three times. In the engineering of electro-optical stabilization servo mechanism  -- filter has properties of tracking differential  and reached the requirement of platform angular velocity estimation. Also it is one of the effective methods to get angular velocity from angular position sensors. 2011 IEEE.   论间接占有 学位论文 2011, 2011 王娜 收藏  |  浏览/下载：2/0  |  提交时间：2016/02/14 间接占有  性质和功能  保护  Indirect possession  Nature and function  Protection   国家立法与社会资源分配的内在逻辑 期刊论文 2009 冯祥武 收藏  |  浏览/下载：3/0  |  提交时间：2016/05/17 国家立法  社会资源分配  功能与本质  内在逻辑  state legislation  allocation of social resources  function and nature  internal logic
