How does the Simulink PID-Autotuner work?

In my Bachelor-Thesis I want to stabilize a one-wheeled robot with a PID-Controller. Therefore I build a simple model of the robot in Simulink. This is a SISO-System (Input is the angle, output is the speed of the wheels).

In Simulink I want to use the PID-Autotuner to get the PID-parameters.

First Question: How does the PID-Autotuner work? I would feel much more comfortable if I could at least name the algorithm that Simulink uses. Otherwise this great tool is very dark black box in my thesis..

Second Question: Does anyone see a reason why my plan could not work? Mybe I've overseen something which is obvious for someone else..?

Thank you for your help! Greetings from cold Munich

PID Tuner uses a proprietary algorithm that we developed and patented. So it is bit of black box. This doc page describes the algorithm in pretty general terms.

Your plan looks good.

Good luck.
