The Small Disturbance Problems Associated with the Algebraic Riccati Equation of Continuous Linear Time-Invariant Systems

摘要: 本文讨论了连续型线性定常系统摄动的Riccati代数方程所对应的稳定性问题.通过矩阵范数分析建立了摄动的Riccati代数方程的解的摄动界估计(以系统参数摄动界表出),从而提供了一种方便的实用计算方法.

Abstract: The stability problem of the disturbed algebraic Riccati equation of continuous linear time-invariant systems is discussed Ln this paper. Through matrix norm analysis the estimation (expressed in terms of the disturbance range of the system parameters) of the disturbance range in the solution of the disturbed algebraic Riccati equation is established. Apparently this method is quite convenient for the practical computational purposes.
