摘要
分别对圆锥运动和伪圆锥运动的产生原因、表达形式,以及对捷联惯导系统的影响进行了分析。由于圆锥运动和伪圆锥运动并不相同,因此圆锥运动补偿算法将对两者产生不同的效果。数字仿真表明,圆锥补偿算法可以大大降低经典圆锥运动对捷联导航系统的不利影响,但同时却会增大伪圆锥运动对捷联导航系统的不利影响。因此在实际应用当中,应当结合圆锥运动和伪圆锥运动对系统的影响比重,选择合适的圆锥补偿算法。
The causes and models of coning motion and pseudo coning motion as well as their influences on strapdown inertial navigation system (SINS) were analyzed. Since these two kinds of motions are different, their effects on coning motion and pseudo coning motion given by coning compensation algorithms are not the same. The simulation result indicates that although coning compensation algorithms can minify the unfavourable influence of the classic coning motion to SINS, they can also magnify the unfavourable influence of the pseudo coning motion on SINS. Therefore a coning compensation algorithm should be chosen appropriately to balance the influences of coning motion and pseudo coning motion.
