Starting from the algebraic Riccati inequality (ARI) design H∞control problem, the algebraic Riccati inequality of the robust H∞ estimator is simplified by selecting the parameter matrices M and N. Then the robust matrix design method is derived by using the linear matrix inequality H∞ estimator theorem. The example shows that the estimator designed has good robustness
