Stability Analysis of Switched Systems-A Variational Approach

We review a variational approach for analyzing the stability of switched systems under arbitrary switching. This approach was first used to address the celebrated absolute stability problem. The main idea is to characterize the "most unstable" trajectory of the switched system as the solution of a suitable optimal control problem. The variational approach yields the most general results currently available for (1) low-order linear switched systems; and (2) nonlinear switched systems with a nilpotent Lie algebra.
