Abstract

Pneumatic lifting applications are widely used in manufacturing, automotive, and aerospace industries. It uses compressed air to power the pneumatic actuators to move objects, perform tasks, or create force. However, one of the main challenges is accuracy that the lift can overshoot or undershoot the desired setpoint, which can be affected by the friction in the system, the response time of the pneumatic valve and variations in air pressure, temperature, and load. This study aims to address this problem by designing and implementing an embedded Proportional-Integral Derivative (PID) controller for a pneumatic lifting application. The embedded PID controller is integrated into a microcontroller, such as an Arduino. The PID controller was compensated for these variations, resulting in a more accurate and robust system. The advantage of using a PID controller is that it is a simple and effective way to control a system. It is also relatively easy to implement on an embedded system. At the end of this study, an accurate and robust pneumatic lifting system that can be used in a variety of industrial applications was developed
