Abstract

The “Ball Levitation” experiment can be easily recognized, like iFly in Singapore, and is greatly integrated into industrial fields such as flow control systems, aerodynamic testing, the oil and gas industry, HVAC systems, etc. Therefore, it is utilized in university laboratories for student exploration of non-linear control technology. The main objective of this experiment is through the position of the ball which is measured by an ultrasonic sensor to execute the PWM of the blower fan in order to control the speed of one so that the ball can be stabilized consistently at a specific height. Despite its uncomplicated model, the challenge of this model is from non-linear effects on the ball and the intricate physics governing its movement. Moreover, the ball is highly responsive to external influences from the blower fan. Consequently, conventional mathematical control methods struggle to handle it, making the simulation and comparison of control algorithms challenging. A Fuzzy-PID controller is meticulously designed to automatically stabilize the ball's position by considering the PID parameters with pre-defined fuzzy rules due to the actual showcase of the model. This setup allows us to experimentally compare the traditional PID controller with the Fuzzy-PID controller. The results reveal notable differences in the performance characteristics of these controllers.

Abstract

This paper presents an experimental study on the PID algorithm applied to a vehicle system that maintains a fixed distance from an object. The research focuses on how changes in PID parameters affect the vehicle's behavior. The system comprises an SRF05 ultrasonic sensor connected to an Arduino, controlling the vehicle is forward and backward movements to follow the object. Through a series of experiments, analyses, and evaluations, the study explores the effectiveness of the PID controller and addresses challenges. The results help identify the optimal PID parameter values for the system systematically.

Abstract

This paper presents a fuzzy logic control approach for a real ball-in-tube system, which is a classical single-input, single-output (SISO) nonlinear system. The primary objective is to balance the ball's position at a fixed set point while ensuring effective tracking when the reference value changes over time. The results demonstrate the controller's ability to maintain stable ball positioning and provide smooth and responsive tracking behavior in real-time conditions.
