Transfer Functions
· Recall the block-diagram representation of dynamical models. Transfer
Functions compactly represent the linear relationship between
inputs and outputs of a system.
Usually they can be constructed from measured data
· Start with a state-space representation x = Ax + Bu, y = Cx + Du
· Consider inputs of the form
