Model Browser User's Guide

What Is the Model-Based Calibration Toolbox?

The Model-Based Calibration Toolbox contains tools for design of experiment, statistical modeling, and calibration of complex systems. There are two main user interfaces:

• Model Browser for design of experiment and statistical modeling
• CAGE Browser for analytical calibration

About the Model Browser

The Model Browser is a flexible, powerful, intuitive graphical interface for building and evaluating experimental designs and statistical models.

• Design of experiment tools can drastically reduce expensive data collection time.
• You can create and evaluate optimal, space filling, and classical designs, and constraints can be designed or imported.
• Hierarchical statistical models can capture the nature of variability inherent in engine data, accounting for variation both within and between tests.
• The Model Browser has powerful, flexible tools for building, comparing, and evaluating statistical models and experimental designs.
• There is an extensive library of prebuilt model types and the capability to build user-defined models.
• You can export models to MATLAB, Simulink, or CAGE.

About CAGE

CAGE (CAlibration GEneration) is an easy-to-use graphical interface for calibrating lookup tables for your Electronic Control Unit (ECU).

As engines get more complicated, and models of engine behavior more intricate, it is increasingly difficult to rely on intuition alone to calibrate lookup tables. CAGE provides analytical methods for calibrating lookup tables.

CAGE uses models of the engine control subsystems to calibrate lookup tables. With CAGE you fill and optimize lookup tables in existing ECU software using Model Browser models. From these models, CAGE builds steady-state ECU calibrations.

CAGE also compares lookup tables directly to experimental data for validation.
