Version 2.1 (R2007a) Simulink® Control Design™ Software Release Notes

Version 2.1 (R2007a) Simulink^® Control Design™ Software

This table summarizes what's new in Version 2.1 (R2007a):

New features and changes introduced in this version are

• Ability to Linearize Using an Operating Point Specified Directly in a Model

• Ability to Capture Linearization Snapshots in GUI

• Ability to Perform Control Design at Snapshots in GUI

• Ability to Retrieve Stored Compensator Designs

Ability to Linearize Using an Operating Point Specified Directly in a Model

You can use the Simulink^® Control Design™ software to linearize around any operating point that you specify directly in a Simulink^® model. This capability allows you to make changes to a model and then perform a linearization around the newly specified operating point with the click of a single button. Previously, this same task required two steps: creating a new operating point and then linearizing around this operating point.

There are two ways to linearize around an operating point specified directly in the model:

• From the Controls and Estimation Tools Manager, as described in Linearizing at a Simulink^® Model Operating Point in the Simulink Control Design User's Guide.

• Using linearize. For more information, see linearize in the reference pages.

Ability to Capture Linearization Snapshots in GUI

You can use the Controls and Estimation Tools Manager to linearize at snapshots of your model operating point at the following simulation points:

• Specified simulation times, such as when the simulation reaches a steady state solution, as described in Linearizing at Specified Simulation Times in the Simulink Control Design User's Guide.

• Events during a specified simulation interval, as described in Linearizing at Simulation Events in the Simulink Control Design User's Guide.

As in prior releases, you can use linearize to perform linearization at snapshots in your model operating point, as described in linearize in the reference pages.

Ability to Perform Control Design at Snapshots in GUI

You can use the Controls and Estimation Tools Manager to perform control design at snapshots of your model operating point at the following simulation points:

• Specified simulation times, such as when the simulation reaches a steady state solution, as described in Selecting an Operating Point in the Simulink Control Design Getting Started Guide.

• Events during a specified simulation interval, as described in Selecting an Operating Point in Simulink Control Design Getting Started Guide.

Ability to Retrieve Stored Compensator Designs

When you design a compensator using the SISO design tool, you can store the current design and then continue making changes to this design. A new button called Retrieve Design lets you retrieve the stored design at any time by undoing the design changes you made since you last stored the design. For more information on retrieving stored compensator designs, see Storing and Retrieving Designs in Simulink Control Design Getting Started Guide.
