Abstract

The pneumatic lifting systems are crucial in industries like construction, manufacturing, and transportation for handling heavy loads. However, due to the non-linear behaviour of pneumatic systems, precise control is often difficult, leading to performance inconsistencies and safety risks. This research focuses on developing a Proportional-Integral-Derivative (PID) controller for an Intelligent Pneumatic Actuator (IPA) system. Using the System Identification technique, a 4th-order ARX model was developed to accurately represent the dynamics of the pneumatic system. The PID controller was designed and implemented in MATLAB/Simulink, achieving precise control characterized by fast response times and the absence of overshoot across various position distances of 50mm, 100mm and 150mm. Furthermore, the system maintained steady-state accuracy regardless of load variations from 1kg to 5kg. The results validate the effectiveness of the PID-based control strategy in enhancing the precision and accuracy of pneumatic lifting systems, contributing to more sustainable industrial operations.
