✦ Synopsis

We study the problem of global smooth stabilization of cascade compositions of nonlinear globally asymptotically stable systems. Our main result is that global stabilization can be achieved if we can render the first system strictly passive for an output which spans the "unstable part" of the vector field of the second system. This result generalizes earlier stabilizability conditions for the case when the first system is linear. Also, it provides some insight on the ("energy dissipation") properties of the dependence of the second system vector field and the first systems "output" needed to achieve global stabilization.

A method for designing nonlinear fixed-order (i.e. full-and reduced-order) dynamic passive controllers for passive systems is developed using nonlinear dissipation theory. Specifically, by extending linear passive controller synthesis frameworks a family of globally asymptotically stabilizing nonlin

In this paper a description of a certain class of multiloop systems, called the Standard Multiloop Form, is introduced. This description is expressed explicitly in terms of certain scalar subsystems and can be shown to include many of the common descriptions of multiloop systems. The stability crite
