Abstract

PURPOSE: To realize a free control for the roughness and the fineness of the control property, by securing a proportion between the hysteresis width of the control system and the deviation of the input signal.
CONSTITUTION: The deviation ε between the input signal Ei and the set value Es is supplied to the comparators OP3 and OP4 which have the hysteresis respectively. When the deviation ε larger than the hystresis is supplied, the SW1 or the SW2 is turned on. The deviation ε is supplied also to the hysteresis width setting circuit 6 to produce the output voltage Ea and Eb. Both the Ea and Eb have a size proportional to the ε respectively and then added to the voltage of the input terminal of the comparators OP3 and OP4. As a result, the change proportional to the ε can be applied to the hysteresis width. Furthermore, the ε is integrated by the capacitor CI, and the integrated voltage is added to the outputs of the OP3 and OP4 to be used as the feedback voltage. Thus the deviation voltage is increased virtually to secure the response although the ε is minute.
