Abstract

This paper is two folded: in the first part a result is presented on bounded passivity-based control. This is applied on a reduced-size building model, in order to protect it from earthquakes. The second part of this paper presents an attempt to extend the same methodology towards bounded backstepping-based control. The key point here are the Lyapunov function derivative terms: by manipulating their geometrical shapes, feedback properties follow. On a simple one-dimensional system, we analyze performance, robustness and bounded control.
