Online Estimation

Estimate model parameters and states during system operation, generate code and deploy to embedded targets

Online estimation algorithms update model parameters and state estimates when new data is available. You can perform online parameter estimation and online state estimation using Simulink^® blocks and at the command line. You can generate C/C++ code and deploy your code to an embedded target. To learn more about online estimation, see What Is Online Estimation?

Online ARMAX Polynomial Model Estimation

Implement an online polynomial model estimator. You estimate two ARMAX models for a nonlinear chemical reaction process. These models capture the behavior of the process at two operating conditions. The model behavior is identified online and used to adjust the gains of an adaptive PI controller during system operation.
