What is Simulink good for?
-Modeling/designing dynamic systems
(including nonlinear dynamics)
-Modeling/designing control systems
(including nonlinear controllers and
plants)
-Signal processing design/simulation
Connecting Blocks
Drag a signal line from the output
of a block to the input of another
block.
Ctrl-Click will automatically
connect.
Modifying Block Properties
Double click on any block to
bring up a properties box.
Here are the “sine wave”
properties. If you don’t know
what something is… leave it
alone!!!
Signal Routing
Under the “signal routing” library,
the MUX block can be used to
bundle a group of signals
together into a single line.
The DEMUX block does the
reverse.
This can be useful to:
1. Clear up clutter in a
complicated block diagram.
2. Send multiple signals to the
same scope; then both
signals will be displayed on
the same plot.
Control and Estimation Tool
Select“Tools:Control
Design: Linear
Analysis” from
the simulink
menu.
The control and
estimation tool
will pop up.
Select the type of
plot you want to
generate, and
click “linearize
model”. The
system will be
linearized about
the operating
point (see Ogata
3-10 and
Simulink Help)
