We address state-feedback stabilization of varying-sampling-rate (VSR) discrete-time switched systems (DTSSs), which are systems that describe a continuous-time linear time-invariant system sampled at varying rates. We consider a setting in which the controller, in addition to applying feedback, selects and varies the sampling rate. In this paper we present sufficient conditions for a specific type of VSR-DTSS be stable under arbitrary sampling period switching. Such conditions are based on the solvability of the Lie-algebra generated by specific system matrices. The main advantage is that, as opposed to other existing stabilization techniques, these conditions are based on structural properties of the system.
