Abstract

A design method for on-plant tuning of multivariable PI-controllers for unknown systems is presented. The plant is assumed to be linear, open-loop stable with input delays and subject to step disturbances. The multivariable PI-controller may be tuned with the aid of open-loop step-responses. Finally an example is given to show the applicability of the controller proposed.
