Sampled feedback stabilization of switched continuous-time systems with bounded disturbance and unknown switching

Most practical systems are continuous in nature but with discrete (sampled) feedback. This paper studies the sampled feedback stabilization problem of switched continuous-time systems with bounded disturbance. The system under consideration is assumed to experience model switching consistently with unknown switching process. The only information available is that the switching duration has a lower bound. It is shown that by combining on-line adaptive estimation with sampled feedback control, the system is ensured to be globally stable.
