A method of controlling a process having a control loop using feedback control, including inputting a set point for controlling the process and a controlled variable from the process to calculate a deviation between the set point and the controlled variable, performing one of PI and PID adjustment calculation to make the set point coincide with the controlled variable from the process to output a velocity-type adjustment calculating signal as a manipulated signal to the process, inputting the manipulated signal and outputting a first approximation signal in accordance with a characteristic of an approximated control system, receiving a disturbance signal to be added to the process and outputting a second approximation signal approximated to disturbance characteristic, adding the second approximation signal and the velocity-type adjustment calculation signal and outputting the result, calculating a gain correction ratio signal in accordance with a change in gain of the controller system and a change in disturbance obtained upon a predetermined adjustment, on the basis of the addition result and the first approximation signal, and multiplying the gain correction ratio signal by the controlled variable to perform gain correction of the control loop, and an apparatus implementing the method. |
