The deadbeat control, also known as, finite time settling control is supposed to be effective exclusively in sampled data controls. In 1957, O. J. M. Smith proposed Posicast control to obtain the finite time settling response to a command input for continuous control systems. He mentioned in his paper the finite time settling response to a disturbance as well. His method is, however, impractical because inverse transfer functions of controlled objects would be required.The author has found out a new controller configuration with a delay element for continuous control systems, which has the finite time settling responses both to a step command input and to a step disturbance. This new method is named Continuous deadbeat Control (CdbC) and was published.This paper describes a design of CdbC. Conditions to realize controllers based on CdbC are shown, and the following is cleared. For a high order controlled object without unstable zeros, only one delay element is required in the controller independent of functions of a command and a disturbance.
