I am doing on project on Auto tuning of a controller using Arduino Due, whereby I am looking forward to control a DC motor (http://ww​w.pololu.c​om/product​/1444) using PID and relay feedback method.

At this moment I am stuck on controlling the speed of the motor. However I needed more information on how to display the current speed of the motor on Simulink. Attached below is the Simulink model that we are using.

Looking for some ideas on how to go about using a PID controller and control the motor.

Thanks

Yes I have already worked on that example. However, in that example they are using a different encoder compared to the one that I am using (<http://www.pololu.com/product/1444)>. I am having problems in displaying a constant rpm of the motor using that example. Kindly requesting if you could help. Thanks
