摘 要: 对于在状态估计和多传感器信息融合领域遇到的Lyapunov方程,用矩阵理论证明了Lyapunov方程迭代解的指数收敛性,且证明了收敛速度被Lyapunov方程中的两个矩阵的谱半径决定。当谱半径明显小于1时,可实现得到Lyapunov方程解的快速算法。 For the Lyapunov equations to occur in the state estimation and multisensor information fusion fields, the exponential convergence of the iterative solution to Lyapunov equation is proved by matrix theory, and it is proved that the convergence rate is determined by the spectral radiuses of two metrices in Lyapunov equation. When the spectral radiuses are obviously less than 1, a fast algorithm to obtain the solution of Lyapunov equation is realized.
