Estimation Projects

Structure of an Estimation Project

The Control and Estimation Tools Manager, which is a graphical user interface (GUI) for performing parameter estimation, stores and organizes all data from a given Simulink® model inside a project. To open the Control and Estimation Tools Manager GUI, select Analysis > Parameter Estimation in the Simulink model window.

When using the Control and Estimation Tools Manager for parameter estimation, you can

  • Manage estimation projects.

  • Select parameters and initial conditions to configure the estimation.

  • Specify cost functions.

  • Import experimental data (to be matched by the output of your Simulink model).

  • Specify the initial conditions of your model.

Each estimation task can include

  • One or more data sets

  • Parameter information

  • One or more sets of estimation settings, or configurations

The default project name is the same as the Simulink model name. The project name is shown in the Workspace tree of the Control and Estimation Tools Manager.

You can also add tasks from Simulink Control Design and Model Predictive Control Toolbox software to the current project, if these products are installed on your system.

Managing Multiple Projects and Tasks

The Control and Estimation Tools Manager works seamlessly with products in the Controls and Estimation family. In particular, if you have licenses for Simulink Control Design™ or Model Predictive Control Toolbox™ software, you can use these products to perform tasks on projects that you have created in Simulink Design Optimization™ software, and vice versa.

This figure shows a tools manager with multiple projects and multiple tasks.

You can save projects individually, or group multiple projects together in one saved file, as described in:

Adding, Deleting and Renaming an Estimation Project

To add, delete, or rename the project or task:

  1. Right-click the project or task node in the Workspace tree.

  2. Select the appropriate command from the shortcut menu.

Saving Control and Estimation Tools Manager Projects

A Control and Estimation Tools Manager project can consist of tasks from products such as Simulink Control Design, Simulink Design Optimization, and Model Predictive Control Toolbox software. Each task contains data, objects, and results for the analysis of a particular model.

To save your project as a MAT-file, select File > Save in the Control and Estimation Tools Manager window.

To save multiple projects within one file:

  1. In the Save Projects dialog box, select the projects that you want to save.

  2. Click OK.

  3. Choose a folder and name for your project file by either browsing for a file or typing the full path and filename in the Save as field. Click Save.

Loading Control and Estimation Tools Manager Projects

To open previously saved projects, select File > Load in the Control and Estimation Tools Manager window.

In the Load Projects dialog box, choose a project file by either browsing for the folder and file, or by typing the full path and filename in the Load from field. Project files are always MAT-files. The projects within this file appear in the Projects list.

Select the projects that you want to load, then click OK. When a file contains multiple projects, you can choose to load them all or just a few.
