【 摘 要 】

This paper describes a method for designing optimal feedback controllers with stability requirements using low-order Riccati equations. For originally stable systems the Riccati equation will be of first or second order, depending upon whether the eigenvalues are real or complex. For originally unstable systems the order of the Riccati equation will be equal to the number of eigenvalues with positive real part.
