Abstract

PURPOSE:To stabilize a controller at the time of a fault, by decreasing an output of a correcting circuit to ''0'', and inputting it to a control system as the extent of correction of a target value or the extent of correction of a manipulated variable. CONSTITUTION:When an output of a switching device 22 is ''0'', an output of an element 20 of time lag of first order is reset to an output DELTAr of a computer 7, therefore, DELTAr is inputted to an adder 8 as it is. Subsequently, when the output of the switching device 22 is ''1'', the output of the element 20 is decreased like an exponential function toward a value of ''0'' generated by a zero generator 21, and becomes ''0'' finally. Accordingly, at the normal time, the output of the computer 7 is inputted to the adder 8 as it is, but the moment that the output of the device 22 has become ''1'', the output signal of the computer 7 is intercepted smoothly by inputting a signal gradually decreasing to ''0'' like an exponential function with a set time constant, to the adder 8.
