Simulink Linearization

Flexibility in defining
which portion of the model
to linearize

Yes. Lets you specify linearization

I/O points at any level of a

Simulink model, either graphically

or programmatically without

having to modify your model. See

“Linearize at Trimmed Operating

Point” on page 2-90.

No. Only root-level linearization

I/O points, which is equivalent to

linearizing the entire model.

Requires that you add and

configure additional Linearization

Point blocks.

Open-loop analysis Yes. Lets you open feedback loops
without deleting feedback signals
in the model. See “Compute Open-
Loop Response” on page 2-64.

Yes, but requires that you delete

feedback signals in your model to

open the loop

Control linear model state
ordering

Yes. See “Order States in

Linearized Model” on page 2-135.

No

Control linearization of
individual blocks

Yes. Lets you specify custom

linearization behavior for both

blocks and subsystems. See “When

to Specify Individual Block

Linearization” on page 2-161.

No

Linearization diagnostics Yes. Identifies problematic blocks
and lets you examine the
linearization value of each block.
See “Linearization
Troubleshooting Overview” on
page 4-2.

No

Block detection and
reduction

Yes. Block reduction detects blocks

that do not contribute to the

overall linearization yielding a

minimal realization.

No

Control of rate conversion
algorithm for multirate
models

Yes No
