โœฆ Synopsis


Stone-Weierstrass theorem is extended and used to develop a general theorem on representations of bounded, continuous, time-invariant, causal nonlinear systems which allows one to construct representations with desired structural properties. The general theorem encompasses the classic series of Volterra, Wiener, and Barrett as well as Zadeh's hierarchy. Application to system identification is discussed.

A simple, but fundamental, theorem is given on the extent to which a nonlinear system model can have its order reduced. EssentialIy, the result is that the order, or the dimension of the state space representation, cannot be reduced to, or below, the dimension of the system's attractor. Several exam
