摘要


我們要做的是研究一個來自於不定隨機線性二次控制問題和隨機H∞控制問題的隨機代數黎卡迪方程式。 我們獲得一個擾動的界並且分析擾動的SARE的穩定解的存在性。數值例子也說明該擾動界的精確度。

In this work we study a class of stochastic algebraic Riccati equations from the indenite stochastic linear quadratic control problems and stochastic H∞ control problems. We obtain a perturbation bound for the stabilizing solution of the perturbed and analyze the existence of stabilizing solution to the perturbed SARE. A numerical example is presented to illustrate the sharpness of the perturbation bound.
