A new separation result for a class of quadratic-like systems with application to Euler-Lagrange models. (English) Zbl 1021.93030
The authors consider the problem of output feedback stabilization for a class of time-varying systems roughly quadratic in the unmeasured states. This includes, in particular, Euler-Lagrange systems. Since a tracking problem for a system can be reformulated as a stabilization problem for the time-varying error system, the authors’ results give a solution to the tracking problem for Euler-Lagrange systems as a consequence.
