An interactive software tool for the study of event-based PI controller

The paper describes an interactive tool focused on the study of a new family of event-based PI controller. Most research in control engineering considers periodic or time-driven control systems. Event-based control is particularly a very promising alternative when systems with reduced computation and communication capacities are considered. For event-driven controllers it is the occurrence of an event, instead of the autonomous progression of the time what decides when the signal sampling should be made. The tool has been developed using Sysquake, a Matlab-like language with fast execution and excellent facilities for interactive graphics. The highly visual and strongly coupled nature of event based control system is very amenable to interactive tools. The tool presented in this paper enables to discover a myriad of important properties of these systems.
