| Abstract: | In this paper the quadratic optimum problem in discrete system is discussed in terms of energy. The necessary and sufficient condition for the existence of optimal control is obtained, and the uniqueness and feedback property of optimal control are proved. Using this extended quadratic optimization theorem, the necessary and sufficient condition for the existence of stable quadratic optimal closed-loop system is obtained. |
