Abstract
A technique is presented to increase the damping in a closed-loop discrete-time system by modifying a nominal linear quadratic performance criterion. The technique relies on the existence of more than one solution to the discrete-time algebraic Riccati equation and on the modification of the nominal solution, which leaves selected eigenvectors invariant. The increased damping is achieved by moving the nominal closed-loop eigenvalues to an exact location along the line segment connecting the nominal eigenvalues with the origin.
