Overview of Parameter Estimation

When you estimate model parameters, Simulink Design Optimization software compares the measured data with data generated by a Simulink model. Using optimization techniques, the software estimates the parameter and (optionally) initial conditions of states to minimize a user-selected cost function. The cost function typically calculates a least-square error between the empirical and model data signals.

After you import and preprocess the estimation data, as described in Importing Data into the GUI and Preprocessing Data in the GUI, follow these steps to estimate model parameters:

1. Creating an Estimation Task

2. Specifying Data for Parameter Estimation

3. Specifying Parameters to Estimate

4. Specifying Initial States

5. Selecting Views for Plotting

6. Specifying Estimation Options

7. Performing Estimation

8. Performing Validation

Note   The Simulink model must remain open to perform parameter estimation tasks.

To learn how to estimate parameters at the command line, see Estimating Parameters at the Command Line.
