Abstract :

The ball and beam system is one of the most popular laboratory setups for control education. In this paper, we design a fuzzy PD cascade controller for a ball and beam system using Asexual Reproduction Optimization (ARO) technique. The ball & beam system consists of a servo motor, a grooved beam, and a rolling ball. This system utilizes a servo motor to control ball’s position on the beam. Changing the angle of servo motor results in the movement of the beam and, subsequently, the ball rolling on it. We designed a fuzzy PD cascade and a PD cascade controller scheme which consists of the two controller loops. The first (outer) controller and the second (inner) controller are organized in a cascaded construction.
