【Abstract】 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.
