Revisiting the Ziegler-Nichols tuning rules for PI control

På svenska

Author

Summary, in English

This paper presents new tuning rules for PIcontrol of processes with essentially monotone step response that aretypically encountered in process control. The rules are based oncharacterization of process dynamics by three parameters that can beobtained from a step response experiment. The rules are obtained bymaximizing integral gain subject to a constraint on themaximum sensitivity. They are almost as simple as theZiegler-Nichols tuning rules but they give substantially betterperformance.
