The Options dialog box includes the following updates to the
descent

Gradient
command-line changes.
• Algorithm option is renamed to Method.
• Model size option is deprecated and replaced by Algorithm.
When you load a saved project, the software uses the Model size value to
update the Algorithm value automatically.
When you optimize parameters u sing the
Algorithm value other than the default value of
Gradient Descent method, an
Active-Set can lead to a
slightly different result.

Support for Optimization-Based Compensator
Design for Plants with D elays or Specified as
Frequency-Response Data
You can now use optimization-based compensator design for
frequency-response data (FRD) plants or plants with exact time delays in the
SISO Design Tool. For more information, see “Designing Optimization-Based
Controllers for LTI Systems” and “Designing Linear Controllers for Simulink
Models” in the Simulink Design Optimization User’s Guide.

New Parallel Computing Support for Estimating
Model Parameters
If you have the Parallel Computing Toolbox™ software installed, you can use
parallel computing to speed up estimating parameters of a Simulink model.
The parallel computing option is available in the
Gradient descent and Pattern search algorithms. You can enable this
option from either the GUI or at the command line.
Using parallel computing can speed up the estimation time in th e following
situations:

Nonlinear least squares,
Version 1.0 (R2009a) Simulink®Design Optimization™ Software
• The model contains a large number of parameters to estimate.
• The model is complex and takes a long time to simulate.
For more information about using parallel computing for estimating model
parameters, see “Speeding Up Parameter Estimation Using Parallel
Computing” in the Simulink Design Optimization documentation.
Updated Demos
The Simulink Design Optimization demos have been categorized into the
following new categories:
• Parameter Estimation in Simulink
• Response Optimization in Simulink
• Response Optimization in SISO Design Tool
• Design Optimization Using Parallel Computing
• Adaptive Lookup Tables
To open the Simulink Design Optimization demos, type
demo simulink 'simulink d esign optimization'
at the M ATLAB prompt.
Upgrading from Nonlinear Control Design Blockset
Software
Prior to R14, Simulink Response Optimization software was called Nonlinear
Control Design Blockset software. If you are upgrading from Nonlinear
Control Design Blockset software, your models will not work with Simulink
Design Optimization software. To make the models compatible with
Simulink Design Optimization software, use
documentation.
