Modeling Ball and Spinning System

  1. Apr 28, 2015 #1
    How should I go about modelling a ball and spinning beam system in matlab? It's similar to the ball and beam control system except the beam spins like a propeller so the control system has to account for the centripetal force.

    Any reference papers?

    Ever done a Simulink model of the ball and beam control system? If not, start there. In case you haven't done any work yet on this, you'll have to draw some sort of diagram and get your equations of motion and kinematics right. I would suggest using Lagrange for that. Give us some more details on the work you've done already and maybe we can help.

    I believe I have found some Simulink models of the ball and beam control system and I've got them working in matlab. I'm working on the kinematics diagram of the ball and spinning beam system now but wouldn't it just be the same as the regular ball and beam system just with centripetal force? I'm not sure how to use Lagrange yet so I need to spend some time on it, but if I was going to start with the kinematic equations, I would use a diagram similar to this one right ?

    or

    And centripetal force would just be a force that is applied on the ball parallel to the beam but in the direction away from the center right?
