Abstract
A technique for increasing the damping in a closed-loop discrete-time system by modifying a nominal linear quadratic performance criterion is developed. The technique uses the multiple solutions of the discrete-time algebraic Riccati equation to modify the nominal criterion. These criterion modifications increase the damping by moving the nominal closed-loop eigenvalues to an exact location along the radial line segment connecting the nominal eigenvalues with the origin
