Precise pressure control is vital in chemical processes involving pneumatic systems, where stability and responsiveness directly impact product quality and safety. This study presented the optimization of a PID control system implemented on the mathematical model of a PCT-14 pressure control trainer. A Genetic Algorithm (GA) was employed to determine the optimal values of PID parameters (Kp, Ki, Kd) that minimize overshoot, settling time, steady-state error, and integral time-weighted absolute error (ITAE). The results showed that the GA-tuned PID controller outperformed conventional tuning methods, such as Skogestad's and GoodGain method, providing smoother, faster, and more accurate control of air pressure in the simulated reactor. © 2025 IEEE.
