Internal resonance in pneumatic regulators can result in heavy leakage, which can lead to less efficient processes. To address this issue, two simulations were developed to simulate pneumatic regulation systems. The first simulation involved deriving a mathematical model of the equations of motion for a regulator and applying it using MATLAB. The second simulation involved developing a Simulink model that incorporated physical regulator properties. To verify the accuracy of both models, physical testing data was used. After verification, the models were modified in various ways to determine the main drivers of resonance in pneumatic systems. Additionally, Finite Element Analysis was conducted to observe the modal frequencies of the regulator using Autodesk Inventor. The investigation yielded valuable tools that will aid in mitigating resonance in both existing and future regulator designs. These findings can be used to optimize pneumatic systems for better efficiency and reduced leakage, leading to increased process effectiveness. Ultimately, this research contributes to the improvement of pneumatic regulation systems and enhances the overall performance of industrial processes.
