Abstract

A differential operator approach to modeling the dynamical behavior of linear, time-invariant, multivariable systems is employed in order to develop some new techniques for determining the controllability and observability properties of series, parallel, and feedback composite systems. The tests outlined involve polynomial matrix manipulations and rely on some recent results which deal with the controllability and observability of systems in differential operator form.
