Comparison of some tuning methods for integrating processes

There are several tuning methods available for PI controllers. The Magnitude Optimum Multiple Integration (MOMI) tuning method results in a very good closed-loop response for a large class of process models. The method calculates the PI controller parameters from the process model or from the open-loop or the closed-loop time response of the process. Recently, the MOMI tuning method has been extended for integrating processes. This paper is giving comparison of MOMI tuning method with some other PI controller tuning methods for integrating processes. It is shown that the MOMI method is comparable or even better than some of compared methods.
