Controllability and observability of dynamic systems (Q1178660)

This is a survey on controllability and observability of autonomous linear control systems. The section headings are: 1. Introduction; 2. Controllability of dynamic systems; 3. Observability of dynamic systems; 4. Controllability and observability of infinite-dimensional systems; 5. Conclusions. Some merits of this survey should be noted: the presentation is clear and attractive; several open problems are presented; the list of references contains 88 titles.
