Robust sampled-data stabilization of linear systems: an input delay approach. (English) Zbl 1072.93018
The authors develop necessary LMI conditions for checking whether a linear static state feedback asymptotically stabilizes a linear sampled-data system with known bound on the sampling rate. The results are obtained by interpreting sampling as a time-varying uncertain delay and by representing the resulting system in descriptor form. The LMIs are show to be feasible for continuous-time stabilizing controllers under sufficiently fast sampling. Extensions to saturated feedback laws are also discussed.
