摘要
在某些航姿系统中 ,陀螺采用角速率信号输出。针对这种情况 ,作者推导了几种航姿算法的圆锥运动误差表达式 ,并且在理论上比较了它们的误差。
In some attitude determining systems,the angular rates of gyros are used as their outputs. In this paper,the estimation errors of several algorithms under the condition of coning movement are derived.The error estimation equations provide a method to study the errors of these algorithms.Both theory derivation and the followed simulation show that quaternion algorithm is relatively effective when only angular rate signal is given.
