Abstract

PURPOSE:To decide the generation of hunting, through the number of times exceeding a prescribed number for the decrement from a maximum value of a control variable or the increment from a minimum value of it. CONSTITUTION:A low selector 1 holds a minimum value of a controlled variable (e) and reset to wait for the detection of the next minimum value when a max- imum value is confirmed. Similarly, a high selector 2 holds the maximum value of the controlled variable (e) and reset to wait for the detection of the next maximum value when the minimum value is confirmed. A deviation monitor circuit 5 outputs a minimum value deciding signal by confirming that the value (e) passes through the minimum value and turns upward, and a deviation monitor circuit 6 outputs a maximum deciding signal by confirming that the value (e) passes through the maximum value and turns downward. An FF8 stored the nearest minimum value and an FF9 stores the nearest maximum value. A counter 15 detects that (n) sets of minimum and maximum value deciding signals while a timer 16 counts time and outputs a hunting generation signal.
