Fuzzy Logic Based Ball on Plate Balancing System Real Time Control by Image Processing

摘要

Recently, new control methods have emerged along with developing control methods. Fuzzy logic is one of the new and developing controlmethods. In some cases, it is more adequate to control complex systems using fuzzy logic controller. In this study, a dynamic position of the ballon the plate was controlled by determining the angle of the plate in real time with fuzzy logic control method. The ball position was obtainedby a digital camera and the image was processed in MATLAB/Simulink environment. Fuzzy logic algorithm was built according to the systemunder investigation. The output obtained from the serial port interface is sent to microcontroller card and the motors in the system are activatedto the desired angle to keep the ball on the plate and to avoid falling of the ball. For this, a fuzzy logic controller was designed for ball balancingsystem on the plate. The system is controlled successfully and the controller performance are tested.
