In many industrial control processes, the control of the precise position of a valve, a cylinder, or any other mechanical linkage may be desired. In order to gain experience in the construction and precise control of physical plant systems, a laboratory scale model of a ball and beam balancing system has been designed, built and analyzed. The system consists of a ball, a beam which incorporates a position sensor, a servo motor and a power amplifier. In this presentation, we will discuss the mathematical model of the system, the hardware and different compensator designs.
