【Abstract】 Based on Lyapunov theory ,this paper studies the bounds estimation of state covariance matrix for stochastic system when the system matrix and the noise input matrix have mismatch perturbations.Given solutions of two algebratic Riccati equations,the upper and lower bounds for covariance matrix are proposed and the application of the above methods in fire control model simplification is introduced.更多还原
