How do I model Electrical braking roller using Simulink or Simscape

I am currently working on a electrical braking roller used in cargo handling system. I have to connect a motor parallel to the roller and check the speed based on the emf produced in the motor, and brake the roller automatically if the speed increases more than certain level.

How to proceed modelling for this system?

I need this for my intern project.

This answer is being provided late as part of an effort to clean up Matlab Answers:

You will need to model a few things.

1. you need to pick the correct model of your motor. These can be found in Simscape Electrical
2. you need to have a controller for your motor.
3. you need to create simulink logic to detect the speed of the motor, and use that signal to tell the controller to slow the system down.
4. You need a model of the roller. A basic model should be possible with the rotational mechanical elements in Simscape but a more advanced one could be modelled using driveline if you need gears or anything along those lines.

To assist with this, you will probably need some training in the tools. Here are free trainings for the relevant tools:
