| Summary: | In engineering applications, such as in micro hand surgical systems, airport baggage transfer conveyors, and the semiconductor production business, industries have proven the applications of lighter, stronger, and more flexible plates. Nonetheless, the system may exposed to low frequency vibration due to the structure that can easily impacted by outside influences. In this report, active vibration control (AVC), which employs a Proportional-Integral-Derivative (PID) controller, is provided as a means of reducing low frequency vibrations in flexible horizontal plate systems. The PID controller's parameters for the flexible plate systems with boundary conditions of clamp-clamp-clamp-clamp edges constrained at the horizontal position are optimized using the Advanced Firefly Algorithm (AFA). Subsequently, the performance and effectiveness of PID-AFA was evaluated and compared against its standard algorithm, Firefly Algorithm (FA). Validation test was conducted by finding the lowest Mean Squared Error (MSE) and largest vibration attenuation. The results obtained proved the superiority of PID-AFA by achieving smallest MSE of 4.7790x10-6 and vibration attenuation up to 45.85%, at its dominant first mode vibration. © 2024 IEEE.
