Ball and Beam Model
The model of a ball on an inclined plane represents the processes occurring in the control of unstable systems typically found in aerospace. The system models the problems that must be faced by, for example, aircraft designers to stabilize and optimize aircraft behavior during takeoff, flight, and landing. The model is connected to the computer via a multifunctional input/output card that allows reading outputs and setting inputs. This teaching aid was purchased in 2011 from the resources of the Grant Programme of the South Bohemia Region "Introduction of new technologies into secondary and higher vocational schools". The price was 164 816 CZK.
Interface inputs and outputs
- Inputs: motor voltage u [V]
- Outputs: angle of the plane α [°], position of the ball x [m]
Used for teaching
- SS: verification of physical laws in mechanics (Newton, friction)
- SS: measurement of static transmission characteristics of a sensor
- TTS: modeling and identification of dynamic systems
- TTS: design of the control of the inclination of a plane by a PID controller
- TTS: ball stabilization by PID controller (multi-loop control)
