Modeling Ball and Spinning System

AI Thread Summary
To model a ball and spinning beam system in MATLAB, it's essential to account for centripetal force, which affects the control dynamics. Starting with a ball and beam control system as a reference is recommended, and creating a kinematic diagram will help in deriving the equations of motion. Using Lagrange's method is suggested for formulating these equations, though some users may need to familiarize themselves with it first. Resources like existing Simulink models and kinematic diagrams can provide valuable insights. Properly integrating these elements will lead to a more accurate simulation of the system's behavior.

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 ?

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?

Thread 'I need a concave mirror with a focal length length of 150 feet'

I need to cut down a 3 year old dead tree from top down so tree causes no damage with small pieces falling. I need a mirror with a focal length of 150 ft. 12" diameter to 36" diameter will work good but I can't think of any easy way to build it. Nothing like this for sale on Ebay. I have a 30" Fresnel lens that I use to burn stumps it works great. Tree service wants $2000.

Thread 'Questions about the Tesla turbine'

Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...

My water meter is submerged under water for about 95% of the year. Today I took a photograph of the inside of my water meter box because today is one of the rare days that my water meter is not submerged in water. Here is the photograph that I took of my water meter with the cover on: Here is a photograph I took of my water meter with the cover off: I edited the photograph to draw a red circle around a knob on my water meter. Is that knob that I drew a red circle around my meter...
