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.   Research on the filter technology of DC/DC converter output terminal (EI CONFERENCE) 会议论文  OAI收割 2009 3rd IEEE International Symposium on Microwave, Antenna, Propagation and EMC Technologies for Wireless Communications, MAPE 2009, October 27, 2009 - October 29, 2009, Beijing, China 作者:  Wang W.;  Wang W. 收藏  |  浏览/下载：26/0  |  提交时间：2013/03/25 In order to filter out the common-mode and differential-mode interference of DC/DC converter output power  restrain the power's ripple  reduce the transmitting interference of power  and increase the anti-interference ability and stability of power system  we analyze the internal structure of DC/DC converter  describe its working principle  and take mechanism analysis of the noise produced by it. According the result  I will bring forward the integrating nonlinear filter method as well as introduce the designation and calculation method of filter inductance. According to the experiments  the power of this system works stably and satisfies the output need of system's power. 2009 IEEE.
