Abstract:
A process control apparatus for controlling a control target includes, but is not limited to, first and second control units. The first control unit is designed in a design environment unspecifying any period of disturbance. The first control unit performs a feedback control to the control target by using a setting value of the control target and a measured value of the control target. The first control unit is included in a feedback loop. The second control unit is also included in the feedback loop. The second control unit is designed by using an internal model principle. The second control unit rejects the disturbance, which is applied to the feedback loop, by using the measured value of the control target.
