Abstract

This paper considers the conditions under which one can model the system's output, or any other transformation of the state, by a model of reduced-order. It is shown that a model of the same "dimension as the output vector is possible to obtain only under very restrictive conditions with strong implications. When a more general model is attempted it Leads to tho development of a new canonical form for linear dynamic systems with a scalar output. It is further shown that every such canonical form has an observer embedded in its structure whose elements can be picked out by inspection.
