摘要: |
本文研究了部分参数不准确的线性系统的H∞状态估计滤波问题,或即参数鲁棒性H∞估计问题。我们先把它简化为带δ参数的对象的H∞状态估计滤波问题,采用J无损分解方法,推导出可解性条件和滤波器的全部显式通解。 |

Abstract: |
This paper is concerned with H∞ state estimation filter problem for linear systems with part of the parameters uncertainty-the parameter robust H∞ estimation problem. It can be simplified to a H∞ state estimation problem for a plant with a scaling parameter δ. We deduce a solvability condition and give an explicit expression of the complete solution set for the robust H∞ filter by J- Lossless factorization method. |
Keywords: parameter robustness H∞ estimation H∞ standard control problem J lossless factorization |
