ABSTRACT:
A system for controlling a process system subject to an external disturbance by adjusting a value of a control amount outputted by the process system to a given target value. The system includes a difference computing unit for computing a difference between the control amount value and the given target value, a main control unit for performing at least proportional and integral control operations from a choice of proportional, integral and differential control operations based on control constants including proportional gain, integration time, and derivation time adjusted to a first given state that suppresses fluctuation of the control amount produced by external disturbance, and a compensation control unit for performing a compensation control operation to equivalently adjust the control constants of the main control unit to second given state that tracks target value variation.
