Adjust Plant Structure and Parameters

PID Tuner allows you to specify a plant structure, such as One Pole, Two Real Poles, or

State-Space Model. In the Structure menu, choose the plant structure that best

matches your response. You can also add a transport delay, a zero, or an integrator to

your plant.

In the following sample plot, the one-pole structure gives the qualitatively correct

response. You can make further adjustments to the plant structure and parameter values

to make the response of the estimated system a better match to the measured response

data.
