Local Model Class: Linear Models
Select Linear Models and then click Setup.
You can now set up polynomial or hybrid spline models. The settings are exactly the same as the global linear models.
These models are for multiple input factors - for single input factors you can use a different polynomial model from the Local Model Class list, where you can only change the polynomial order. See Local Model Class: Polynomials and Polynomial Splines.
If there is more than one input factor, you can only choose Linear Models or Transient Models from the Local Model Class list. Under Linear Models you can choose Polynomial or Hybrid Spline. This polynomial is a different model where you can change more settings such as Stepwise, the Term Editor (where you can remove any model terms) and you can choose different orders for different factors (as with the global level polynomial models).
See Global Linear Models: Polynomials and Hybrid Splines for details.
Different response features are available for this Linear Models: Polynomial model and the other Polynomial choice (for single input factors). You can view these by clicking the Response Features tab on the Local Model Setup dialog. Single input polynomials can have a datum model, and you can define response features relative to the datum. See Datum Models.
These linear models are labelled Quadratic, Cubic etc on the test plan block diagram, while the single input type of polynomials are labelled Poly2, Poly3 etc.For higher orders both types are labelled Poly n.
Local Model Class: User-Defined Models
You must check user-defined models into the Model-Based Calibration Toolbox before you can use them here. The only model checked in by default is Exponential.
See User-Defined Models of the Technical Documents for detailed instructions on this.
Local Model Class: Transient Models
These are supported for multiple input factors, where time is one of the factors. You can define a dynamic model using Simulink and a template file that describes parameters to be fitted in this model. You must check these into the Model-Based Calibration Toolbox before you can use them for modeling.
See Transient Models of the Technical Documents for detailed instructions and an example.
