PROBLEM TO BE SOLVED: To provide a process control device, capable of effectively eliminating the effect of disturbance as needed without reconfiguring an existing feedback loop. SOLUTION: The process control device 1 includes a controller 11, a plug-in disturbance removing controller 12, and a primary filter 13 and performs control of a control object 30. The controller 11 is designed in an environment without specification of the period of disturbance, and performs feedback control of the control object 30 using a set value r to the control object 30 and a measurement value y of the control object 30 through the primary filter 13. The plug-in disturbance removing controller 12 is added to a feedback loop containing the controller 11, and designed using an internal model principle so as to remove the disturbance applied to the feedback loop using the measurement value y of the control object 30.
