【Abstract】 The physics and controlled demands of the weight belt balance are dissected. A design scheme of hardware and software for engineering realization and two general expressions of twice optimum algorithm for delay system are presented. Them alread succeed in applying to computer controlled burdening system in cement production line. The results verify that performance of discrete digit algorithm of twice optimum control is similar to continuous analog algorithm of twice optimum control and suited to valiable delay object. It is an efficient algorithm for engineering design.更多还原
