A behavioral approach to time-varying linear systems. Part 1: General theory

摘要

We develop a behavioral approach to linear, time-varying, differential-algebraic systems. The analysis is "almost everywhere" in the sense that the statements hold on RT, where T is a discrete set. Controllability, observability, and autonomy are introduced and related to the behavior of the system. Classical results on the behavior of time-invariant systems are studied in the context of time-varying systems.
