Image Fuzzy Control on Magnetic Suspension Ball and Plate System

This paper presents a fuzzy logic control (FLC) implementation on a ball and plate system for dynamic control verification using CCD position sensing. A two degree-of-freedom (DOF) platform is constructed for experiments using four magnetic suspension (MS) actuators. The mathematical model of the ball and plate operation is derived in Euler-Lagrange equation. From CCD position sensing, a microcontroller is implemented to control MS actuators by PWM current drivers. The position tracking performance on the MS ball and plate system is verified on different cases by adopting an enforced fuzzy logic controller.
