Title: Funnel control: origin and recent advances by Stephan Trenn
Abstract: Funnel control is a powerful and simple nonlinear control method to solve the output tracking problem for uncertain systems with prescribed transient performance as well as with guaranteed accuracy. The origin of the funnel controller can be seen in (adaptive) high gain feedback, and the funnel controller resolves the major problems of high-gain feedback; in particular, arbitrary reference signals can be tracked arbitrary well and the feedback gain is not monotonically increasing. A simple proof is provided why the funnel controller works and further theoretical extensions are discussed and illustrated with experimental setups and simulations.
Title: Krasovskii passivity by Michele Cucuzzella
Abstract: In this talk a new passivity concept named Krasovskii passivity will be introduced and novel Krasovskii passivity based control techniques will be presented, including consensus protocols. The usefulness of the proposed methodologies is demonstrated through the design of controllers for power networks. Their performance and robustness are validated both through detailed simulations and experimental results, highlighting the practical relevance of Krasovskii passivity–based control.
