Interactively Estimate Plant from Measured or

Simulated Response Data

If you have System Identification Toolbox software, PID Tuner lets you estimate the

parameters of a linear plant model based on time-domain response data. PID Tuner then

tunes a PID controller for the resulting estimated model. The response data can be either

measured from your real-world system, or obtained by simulating your Simulink model.

Plant estimation is especially useful when your Simulink model cannot be linearized or

linearizes to zero.

PID Tuner gives you several techniques to graphically, manually, or automatically adjust

the estimated model to match your response data. This topic illustrates some of those

techniques.

Obtain Response Data for Identification

In PID Tuner, in the PID Tuner tab, in the Plant menu, select Identify New Plant.
