Abstract

This paper discusses the use of actuator devices implementing the so-called generalized sample and hold functions. They will be used in order to develop state feedback controllers that tolerate significant variations in the time interval between samples, frequent in multitasking and networked computer control environments. A particular case is solved via linear matrix inequalities. An experimental DC motor setup has been used to demonstrate the applicability of the approach.
