反馈式组合 meaning in English
feedback combining
Examples
- The algorithm of strapdown inertial navigation system is also discussed and then use the flight - track generator to give a simulation , since a closed loop feedback integrated navigation system is designed in this paper , and the output of the filter must feed back to the strapdown inertial navigation system , the analysis of the algorithm in strapdown inertial navigation system is important . the scheme to design the trajectory of gps and the simulation of gps constellation are then studied , the simulation of gps constellation is given from the calculation of vernal equinox base on the principle of celestial mechanics , this method of different from other methods given by other paper and is useful to the research of satellite navigation system . a new method to abstract noise modal in integrated navigation system is proved to be useful in practice , this method , which is given by use the principles of stochastic processes , statistics , time series analysis , and system identification , is suitable for the kalman filter in integrated navigation system
如航迹产生器的设计，该航迹产生器是研究组合导航问题的前提，从国外一些研究组合导航系统的文献中可以看出，设计这样一个航迹产生器是非常必要的，所以本文自行设计了这样一个系统；还讨论了捷联惯性导航系统中捷联解算的方法，并进行了仿真研究，由于在本文设计的闭环反馈式组合导航系统中，对捷联惯导系统的平台误差进行闭环控制，需要将滤波器输出的校正量反馈到捷联解算内部，所以必须对捷联解算进行深入的研究和分析，更何况捷联解算问题本身也是导航界的一个热门研究课题；另外，本文还介绍了gps轨道及其星座仿真的设计思想和方案，与以往gps轨道和星座仿真不同的是本文从天体力学中计算春分点开始，逐步进行gps轨道及其星座仿真，这样的设计方法对从事卫星导航的研究工作是有价值的；还对组合导航中误差建模方法进行了研究，综合运用随机过程、概率统计、时序分析及系统辩识等方面的理论提出了一套适合组合导航卡尔曼滤波的误差建模方法，并运用实际研究工作中的测量数据对该方法进行了验证。
