Title: Accessibility and feedback linearization of discrete-time systems. 6 p.
Language: Estonian
ABSTRACT. The accessibility problem for nonlinear discrete-time
systems is shown to be easy to tackle by means of standard linear
algebraic tools whereas for nonlinear continous-time systems the
most suitable approach is provided by differential geometry.
The feedback linearization problem for discrete-time systems is
recasted through the language of differential forms. This yields
a solution which is completely constructive. In the event that a
system is not feedback linearizable, the largest feedback
linearizable subsystem is characterized within the same
formalism using the notion of derived flag of a Pfaffian system.
