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 different 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 out of proportional, integral and derivative 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. |
