Based on the method of using a gyroscope in practice  gyroscope error model is established. With the gyroscope error model gyroscope accuracy parameters  that is bias repeatability  bias stability  scale factor  scale factor nonlinearity  output noise and bandwidth  are separately analyzed. According to the concretely required performance indices for an E-O platform  means of distribution of gyroscope accuracy parameters is proposed. A MEMS gyroscope is tested to get the parameters. Bias stability of the gyroscope is 0.08 /s while the bandwidth is 60 Hz. Output noise both at zero input and at nonzero input is analyzed by means of PSD to get the result that nonzero output noise is higher than zero output noise. Frequency response result of the gyroscope is dealt by means of correlation analysis. With all the tested result and the method of distribution of gyroscope accuracy parameters  it is clear that how the gyroscope errors works in an E-O servo system. The principle of distribution of gyroscope accuracy parameters is helpful for choosing appropriate gyroscope for an E-O platform. 2011 IEEE.   Analysis of impact of gyroscope synthetical error on an electric-optical stabilized control system (EI CONFERENCE) 会议论文  OAI收割 3rd International Conference on BioMedical Engineering and Informatics, BMEI 2010, October 16, 2010 - October 18, 2010, Yantai, China 作者:  Zhang X.;  Zhang X.;  Zhang X.;  Jiang H. 收藏  |  浏览/下载：23/0  |  提交时间：2013/03/25 As one of the key components on a seeker  EO stabilized platform on a missile  gyroscope is directly relative to errors of servo systems. Main errors of gyro  such as bias drift and scale factor nonlinearity  are added to a servo system  the result is analyzed to illuminated that how a gyro has effect on a seeker servo system. With the mathematical models of a gyro and a seeker  the principle of choosing a gyro is theoretically deduced first and then two gyros model with different main parameters are added into the same gimbals model  the errors of servo systems are compared to prove the deduction. Final conclusion is helpful for choosing proper gyros in a seeker servo system. 2010 IEEE.
