A new technique for relay based closed loop transfer function estimation is presented. Given a closed loop system and a user selected transfer function, then a relay experiment is used to obtain the frequency corresponding to a selected transfer function magnitude. In this paper the Sensitivity Function is considered. This information can be used to evaluate closed loop properties and/or to redesign the controller.
