Abstract

PURPOSE: To prevent the disturbance of control at the singular point where the gradient of objective of program is changed, by compulsively altering the output to the objective when the process variable approaches to the singular point and taking operation output at the operation end to the start point of operation after that.
CONSTITUTION: The program setter 11 sets the objective with the process, outputs calculates the deviation with the subtraction of the amount of process variable from the objective value at the deviation circuit 12, and operates the controlled quantity in matching with the process variable from this deviation at the integrating operation circuit 13. That is, from the process variable signal and program information of the setter 11, the approach of process variable to the singular point of the objective value or of time is detected 19 to activate the relay 13 instantly. The control signal is outputted, and the controlled output of the operation end in response to the control signal is taken as desired objective with the operation circuit 20 so that the controlled output at the operation end can be the operation start point that. Thus, the disturbance at the singular point where the gradient of the objective of program is changed can be avoided.
