In this chapter a methodology for the performance assessment and retuning of PID controllers applied to integral processes is presented. In particular, the deterministic performance related to both the set-point following and load disturbance rejection task is addressed. Routine operating data are employed in order to evaluate the response obtained with given controller parameters with respect to that achievable with appropriate tuning rules. If the performance is not satisfactory, then the controller is retuned suitably.
