利用AR模型进行动态寻北中有色噪声的控制
Control Methods on Colored Noise by Using AR Model in Dynamic North Seeking
摘要
Abstract
An all-attitude north seeker adopting rotary modulation technology is researched, which employs dynamically tuned gyroscope as angular velocity sensor. In order to control influence of colored noises on dynamic north seeking,AR model of colored noise is established and model parameters are fitted as well as colored noises are predicted by using observation residuals. On the basis of robust estimation,a mixed iterative algorithm based on high breakdown point initial value and assisted by IGG Ⅲ scheme is constructed by using corrected observations. The cal-culations show that fitting and predicting colored noises by adopting AR model can effectively control influence of colored noises on dynamic north seeking. In turn,precision and reliability of dynamic north seeking are improved.关键词
