Abstract

The air levitation system is a non-linear and unstable system. The goal of this work is to develop a low-cost air levitation system. The PID controller is designed and applied to the physically developed system to increase the stability of the system. The platforms that are used to develop and simulate the system consist of the Arduino IDE platform, MATLAB platform, and Simulink platform. The developed system is connected to the Simulink platform for real-time simulation. The transfer functions of the systems are estimated by using system identification technique in MATLAB platform. The PID controller is then designed while the step response is analyzed. The values of the percentage overshoot, rise time, steady-state error, and settling time are investigated. The stability of the air levitation system is increased and it was found that the percentage overshoot, settling time, and steady-state error can be greatly reduced with the application of the PID controller to the system.
