An extension on a reformulation of the algebraic riccati equation problem
F. Carro, Jose Miguel Sanchez Torres · IEEE Transactions on Automatic Control · 1977
In a recent paper [1], a reformulation of the algebraic Riccati equation problem has been introduced when the system has only real roots and under the hypothesis that certain restrictions on the choice of the synthetic output matrixCare fulfilled. In this note the formulation is extended to a wider class of Riccati problems.
