New features and changes introduced in this version are:

Command-Line Interface to the Model-Based Calibration Toolbox Software

The command-line interface to the Model-Based Calibration Toolbox software enables the modeling process to be automated using MATLAB commands. In this way, you can simplify the modeling process for technicians and engineers who might not have extensive background and training in this area. You can also access modeling functionality from test bed automation tools.

Improved CAGE Setup

The CAGE Import Tool allows easier reusability of CAGE sessions. You can use the CAGE Import Tool to import models, data sets, optimizations and features from any Model-Based Calibration Toolbox project file produced in CAGE or the Model Browser (.mat or .cag). This feature can greatly simplify the application of proven feature filling and optimization processes to new engine variants.

Optimization

Optimization in CAGE has had major updates:

Significant speed improvements
New optimization parameters that help avoid local minima by specifying multiple start points, and running only from feasible start points
Automatic scaling of objective and constraint values improves numerical stability of algorithms
Enhanced table filling from optimization results now allows more flexible filling methods: you can exclude infeasible solutions, choose whether to extrapolate, use selected solutions, and apply custom fill algorithms
Enhanced API for user-defined optimization scripts
Improved results visualization for drive-cycle optimizations and multiobjective optimizations
Improved constraint display for non-model constraints (1–D and 2–D tables, ellipsoid, etc.)

Compatibility Considerations

Some existing user-defined optimization scripts may require a call to the function setRunInterfaceVersion to fix incompatibilities. You can also do this in the CAGE Browser GUI in the Optimization Parameters dialog.

If you want to use the new foptcon optimization parameters (multiple start points and run only from feasible start points) with existing optimizations, you must use the menu item Optimization > Reset Parameters.

Calibration Tool Interface

New links to standard industry tools allow import and export of calibrations directly from/to ATI Vision (via a live link or .mat files) and ETAS INCA (via .dcm files).

Boundary Modeling

You can model boundaries using convex hulls. You can create boundary models for subsets of inputs, which simplifies the boundary identification process for complex engines. Improved visualization tools in the Boundary Editor help you construct accurate constraints. Boundary constraints can now be imported into the Design Editor and exported to Simulink.

Feature Filling

The Feature Fill Wizard uses new algorithms to fill and optimize table values with reference to a model. You can fill multiple tables simultaneously using the wizard, extending the range of calibration problems that CAGE can solve. You can impose gradient and smoothing penalties, and fill tables on a region-by-region basis.

Surface Viewer Movie

The Surface Viewer now has a movie mode that is faster and easier to use, with an interactive progress bar.
