In System Identification Toolbox, how can I tune parameters of a transfer function like I can in the PIDtuner when identifying a plant?

In pidTuner, you can identify a plant under "plant -> Identify New Plant". There you can chose the structure of the transfer function: One pole, two real poles, delay, zero, integrator, ... However, I have a transfer function with two zeros, something that I can't find as an option in these possibilities. So I opened the System identification Toolbox in the hope this option is available there. You can chose the estimate Transfer Function Models under "Estimate ->", and indeed you can freely write how many poles and zeros your transfer function has. But after having done the estimate, I would like to tune the parameters in the same way as you can do in the pidTuner. I haven't yet found this in system identification toolbox however. How to solve this?

Hi,
Using the System Identification Toolbox, you can identify process models from measured input-output data in the PID Tuner app in Control System Toolbox. You can interactively adjust system parameters such as gain and pole locations to match model response to measured output. Once the process model is created, the PID Tuner app uses it for automatically tuning PID Controller gains.
The following webinars should be a good point to start.
