Categories : Technology stubs Control engineering. This can be done by selecting the ball's position and velocity as the state variable and the gear angle as the input. It should be noted that the above plant transfer function is a double integrator. The same equation for the ball still applies but instead of controlling the position through the gear angle,we will control the torque applied to the beam directly. A ball is placed on a beam, see figure below, where it is allowed to roll with 1 degree of freedom along the length of the beam. From Wikipedia, the free encyclopedia.

The topic of this thesis was to do an in-depth study of the Ball and Beam process. powerful language for modeling of physical systems, uses the tool Dymola. Ball & Beam: System Modeling. Key MATLAB commands A lever arm is attached to the beam at one end and a servo gear at the other. As the servo gear turns. PDF | The ball and beam system is a classical mechanical system consisting of a ball that moves over a beam in a planar movement.

The beam can rotate.

The ball and beam system consists of a long beam which can be tilted by a servo or electric motor together with a ball rolling back and forth on top of the beam. As such it is marginally stable and will provide a challenging control problem.

This technology-related article is a stub. The equation which relates the beam angle to the angle of the gear can be approximated as linear by the equation below:. Hidden categories: All stub articles.

The second derivative of the input angle actually affects the second derivative of. Even if the beam is restricted to be very nearly horizontal, without active feedbackit will swing to one side or the other, and the ball will roll off the end of the beam.

Mechanical model of the ball and beam system.

The ball and beam system consists of a long beam which can be tilted by a servo or electric Languages. The aims of this research are to model the ball and beam system considering nonlinear factors and coupling effect and to design controllers to control the ball.

This can be done by selecting the ball's position and velocity as the state variable and the gear angle as the input.

For this problem, we will assume that the ball rolls without slipping and friction between the beam and ball is negligible. When the angle is changed from the horizontal position, gravity causes the ball to roll along the beam.

As such it is marginally stable and will provide a challenging control problem. However, for our state-space example we will be using a slightly different model.
