Chirp Signal Based on Linearized Dynamics
Create a chirp input signal based on the dynamics of a linear system. This approach is
useful when you are using frequency response estimation to validate the linearization of
your model.
Open a Simulink model.
model = 'watertank';
open_system(model)
For this example, linearize the model at a steady-state operating point to obtain a state-
space model you can use to initialize the chirp signal.
