摘要
在快速解耦的前提下 ,提出了一种保留非线性的状态估计新算法 ,该算法在保留量测方程非线性的同时又利用了改进的Givens正交变换法 ,从而大大减少了计算量 ,提高了计算速度。
This paper presents a new state estimation method based on retaining nonlinearity and fast decoupling . The method retained nonlinearity in measuring equation, and used the enhanced Givens orthogonal transformation. So it can reduce the amount of calculation and speed up the calculation greatly. A example showed its feasibility.
