"Autopilot Design using Simulink and the Control System
Toolbox"
by Greg
Wolodkin, Karen Gondoly, Pascal
Gahinet
In this article, we consider the design and analysis of an altitude-hold
autopilot using MATLAB®, Simulink®, and
the Control System Toolbox. We begin with a nonlinear Simulink model
of the aircraft's longitudinal dynamics. From this nonlinear model,
we extract linearized models using the Simulink LTI Viewer. We then
use these linear models for control design within the Root Locus Design
GUI. To evaluate our designs, we insert the resulting compensators
back into the Simulink diagram for nonlinear simulation of the closed-loop
system.

"Making Your Own Multiport Simulink Blocks with CMEX
S-functions"
by Paul
Holway
Have you ever needed to implement some action in Simulink but found
that the built-in blocks did not do exactly what you wanted? As you
become more familiar with Simulink, you will find that S-functions
are often the solution. This article will introduce you to some of
the basics of S-functions. At the same time, it will look at a simple
example of a multiport S-function. read
