Simulink Control Design™ - MathWorks

Verify the PID Design in Your Simulink Model

In PID Tuner, you tune the compensator using a linear model of your plant. First, you

find a good compensator design in PID Tuner. Then, verify that the tuned controller

meets your design requirements when applied to the nonlinear plant in your Simulink

model.

To verify the compensator design in the nonlinear Simulink model:

1

In the PID Tuner tab, click to update the Simulink PID controller block with the

tuned PID parameters.

TipTo update PID block parameters automatically as you tune the controller in PID

Tuner, click Update Block and check Auto-update block.

(^2) Simulate the Simulink model, and evaluate whether the simulation output meets your
design requirements.
Because PID Tuner works with a linear model of your plant, the simulated response
sometimes does not match the response in PID Tuner. See “Simulated Response Does
Not Match PID Tuner Response” on page 7-211 for more information.
If the simulated response does not meet your design requirements, see “Cannot Find
Acceptable PID Design in Simulated Model” on page 7-213.
