System Identification

A System Identification Problem example contains a system ID problem formulation and solution. Using the From Workspace or From File block, measured inputs should be input to the system. By subtracting the simulated outputs from the observed outputs, the system ID problem can be reformulated as a disturbance rejection problem. In some cases, you may find it more useful to pass the difference signal through a low pass filter, before applying the constraints.
