Analog Inputs:
RYC-BB. Ball and Beam Module.
The “RYC-BB” Ball and Beam module has been designed to study a practical control system, through
the study of a classical control system; the Ball and Beam Control system.
The “RYC-BB” module consists of two main components: the “RYC-BB” apparatus and the “RYC-BB”
interface box. The “RYC-BB” apparatus contains all the sensors and actuators such as a motor, a wirewound rod that work as a position sensor, etc. and the “RYC-BB” interface box contains all necessary
components for power supplying, signal conditioning, etc.
The components are used in conjunction with the “RYC” unit to control the position of the steel
ball along the beam.
The system allows to insert disturbances manually.
