Ball and Beam Stabilization Laboratory Test Bench With Intellectual Control

Control of unstable plants is very important issue both for technical and for research fields of knowledge. This paper describes the design of laboratory test bench and microcontroller based control system with computer vision application for the ball and beam system stabilization research The goal of microcontroller based control system is to bring the ball to desired equilibrium spot of beam and maintain its position under external disturbances. Ball tracking system is based upon the infrared camera with infrared projector application, beam inclination angle changes with servomotor and control system is written on C language for AVR microcontroller.
