PID Tuner provides several alternatives when linearization fails. In the Plant drop-down
list, you can select one of the following methods:- Import - Import a linear model from the MATLAB workspace.
- Re-linearize Closed Loop - Linearize the model at different simulation snapshot
times. - Identify New Plant - Identify a plant model using measured data.
For this example, click Identify New Plant to open the Plant Identification tool.7 PID Controller Tuning
