SC4026 Fall 2011, dr. A. Abate, DCSC, TU Delft
Lecture 3
Continuation of theory of linear ODE

SC4026 Fall 2011, dr. A. Abate, DCSC, TU Delft 1
Coordinate Shift, Normalization and Scaling
Given a model, can perform basic simplifications on it
coordinate shift
x = f(x) : f(xe) = 0 ~x
.
= x - xe
~x = f(~x + xe)
.
= ~f(~x) : ~f(0) = 0
e.g., affine dynamics
reduce number of parameters and perform scaling (on time, on
variables), to improve numerical conditioning:
