3 4 Why linearization? How to linearize it? Real systems are inherently nonlinear. (Linear
systems do not exist!) Ex. f(t)=Kx(t), v(t)=Ri(t)
TF models are only for linear time-invariant (LTI)
Many control analysis/design techniques are
available for linear systems.
Nonlinear systems are difficult to deal with
Often we linearize nonlinear systems before
analysis and design. How? Nonlinearity can be approximated by a linear
function for small deviations
Use a Taylor series expansion
