Importing a Controller

To import a controller, do one of the following:

• Select the MPC/Import/Controller menu option.
• Select the MPC project/task node in the tree (see Tree View), and then click the Import Controller button.
• Right-click the MPC project/task node and select the Import Controller menu option.
• If you've already designed a controller, select the Controllers node and then click the Import button, or right-click the Controllers node and select the Import Controller menu option.

The MPC Controller Importer dialog box opens. The following sections describe its options:

• Import from
• Import to
• Buttons

Import from

Use these options to set the location from which the controller will be imported.

MATLAB® Workspace

This is the default option and is the case shown in the above example. The Items in your workspace area in the upper-right corner lists all MPC objects in your workspace. Select one by clicking it. The Properties area lists the properties of the selected model.

MAT-File

The upper part of the dialog box changes as shown below.

The MAT-file name edit box becomes active. Type the desired MAT-file name here (if it's not on the MATLAB® path, enter the complete file path). You can also use the Browse button which opens a standard file chooser dialog box.

In the above example, file Controllers.mat contains two MPC objects. Their names appear in the Items in your MAT-file area in the upper-right corner.

Import to

This allows you to specify the MPC task into which the controller will be imported (see example below). It defaults to that most recently active.

Buttons

Import

Select the controller you want to import from the Items list in the upper-right corner. Verify that the Import to option designates the correct project/task. Click the Import button to import the controller.

The new controller should appear in the tree as a subnode of Controllers. (See Tree View.)

The imported controller contains a plant model, which appears in the Plant models list. (See Plant Models View.)

Note    If the selected controller is incompatible with any others in the designated project, the design tool will not import it.

Close

Click Close to close the dialog box. You can also click the Close icon on the title bar.
