Abstract :
A procedure in which a state weighting matrix was modified by introducing a degree of relative stability to relocate the optimal closed-loop eigenvalues of continuous time system was recently presented. This procedure is adapted to relocate the optimal poles to any desired location of a discrete time system. A sequential procedure to relocate the optimal eigenvalues to desired positions by proper modification in performance criterion is developed. The optimal solution of the resulting LQ problem determines the optimal gain, and the closed-loop system attains the desired spectrum. Thus, the desired properties of the Linear Quadratic (LQ) solution are retained, while placing the closed-loop system poles
