We have seen in Chapter 5 how to construct block-diagrams for simulation using integrators and, from there, derive state-space equations. The task was made easier if it was possible to use a chain of integrators, which led to a trivial definition of the state. In many cases that strategy is enough.

Simulating linear systems with non-zero initial conditions
I have discussed in another post how to work with state-space models to simulate the response of linear systems using Matlab’s lsim. It is however also possible to approach this problem from a transfer-function point of view without having to mess with state-space at all.
Simulating linear systems with non-zero initial conditions in state space
Matlab’s lsim function for simulating linear systems will give you the option to provide an initial condition if your system is in state-space but not for transfer-functions.
Simulating linear systems with Matlab’s lsim
In this post we will go over a couple of ways to simulate linear systems in Matlab.
