yaw error
解釋
偏航誤差-
The paper designed aerodynamic control system of pith and yaw channels and roll angle stabilization system, by using unsteady - state error follow - up control theory and state observation station theory in modern control theory
本文使用現代控制理論中的無靜差跟蹤控制系統理論與狀態觀測器理論，設計了俯仰、偏航兩個通道的氣動力控制系統和滾轉角穩定系統。 -
Because the ins error equation is unstable, some initial states error will cause error floating and error accumulating, if the filter observations were only position error, kalman filter will converge very slowly, and some states error ( such as yaw error ) will be great. since the milemeter altimeter and piloting could only output position information, this paper put forward a method, firstly estimateing states and then kalman filtering, to improve filtering effect. simulation proved that this method could effectively reduce the system states error, quicken filtering convergence and improve filtering precision
由於慣導系統（ lsins ）的誤差方程是發散的，某些初始狀態的誤差會引起誤差的漂移和積累，當觀測量只有位置誤差時，卡爾曼濾波的收斂速度很慢，某些狀態（如方位角）誤差很大，而以上除慣導外的其它導航傳感器直接提供的只是位置信息，為了改善濾波器性能，本文根據里程計等傳感器的特點，提出了首先對狀態做出估計，然後在狀態估計的基礎上，進行卡爾曼濾波的方法。
