Abstract

PURPOSE:To control the fluctuation width of the system, which has a time delay, to a small value with a good response, by making one of the status signal of the control object and the reference signal into the pulse signal of a fixed amplitude and by comparing these signals to obtain a turn-on and off control signal. CONSTITUTION:The reference signal is shown by line A, and the conventional status signal is shown by the two-dot broken line. In the conventional example, the turn-on control signal is output by S1', but the status signal rises due to the delay of the control object after t1. Since the turn-off control signal is output by S2' similarly, the status signal rises and falls between -D2 and +D2. In present invention, the status signal is the pulse signal of a fixed amplitude shown by C, and therefore, since the turn-off signal and the turn-on signal are output by S2 and S1 respectively, the status signal rises and falls between -D1 and +D1, and thus, the fluctuation width is controlled to a small value.
