In the DDC System, an analog signal is simulated by digital signals with a zero-order hold circuit. But its sampling period is rather short compared with the time constant of the process. From the point of view of the effective utilization of the controller or the computer, it is desirable to make the sampling period large. This can be done by using the controller which produces the repeated pattern control signal.In this paper, a method is proposed to obtain the repeated pattern signal by sampling the impulse response of the process. By virtue of the repeated pattern signal, the system's output settles within several sampling periods. An acutual controller generating the pattern control signal is produced. It is found from the experimental results of this controller that the proposed method works satisfactorily in a practical system.
