参数不确定系统的鲁棒H_∞估计

Robust H_∞ Estimation for Systems with Parameter Uncertaines

从代数Riccati不等式 (ARI)设计H∞ 控制问题出发 ,通过选取参数矩阵M和N ,对鲁棒H∞ 估计器的代数Riccati不等式进行简化 .再根据Schur补公式 ,导出用线性矩阵不等式设计鲁棒H∞ 估计器的定理 .

Based on the H ∞ design concept by using algebraic Riccati inequalities (ARIs), the ARIs for robust estimation are simplified by selecting special parameter matrices M and N.Then, based on the Schur complement formula, a robust H ∞ estimation theorem with linear matrix inequalities is deduced. The example provided indicated that the estimator has good robust property.
