Discrete Transfer Function

Description

The Discrete Transfer Function component defines the transfer function between the input signal, u, and the output signal, y. The numerator has the order nb1, and the denominator has the order na1.

y=b1znb1+b2znb2+...+bnba1zna1+a2zna2+...+anauz

The state variables, x, are defined according to the controller in canonical form. Initial values of the states can be set as start values of x.

The Signal Size parameter allows the block to operate on a vector of signals rather than a single signal.
