In this paper, a novel control scheme is proposed on the basis of the well-known Smith predictor for the control of integrating processes with long time delay. It can provide one and half degree-of-freedom for the closed loop system tuning. Systematic design procedure is developed by employing optimal control theory, and simple and efficient tuning rules are derived analytically. It is shown that the design procedure can be directly extended to the control of stable processes with time delay. Numerical examples are given to illustrate the proposed method.
