Vibration Control and Seismic Damages Reduction for Structural Buildings Based on Optimal Fractional-Order Controller and a Graphical User Interface Development

Introduction This paper proposes an optimal active vibration control system to control an active tuned mass damper (ATMD), which can help reduce the seismic structural damages caused by the earthquake effects. Methods The proposed controller exploits the features of the fractional-order calculus to improve the performances of the derivative and the integral actions of the conventional PID controller, the parameters gains (Kp, Ki, Kd), lambda and mu of the fractional-order PID controller (FO-PID) are selected optimally using the recent artificial hummingbird algorithm (AHA), A comparative study conducted against the classical PID controller in different earthquake excitations, to highlight the advantages of proposed FO-PID. Finally, A new graphical user interface (GUI) based on MATLAB called "SVCS Structural Vibration Control Simulator" is developed to facilitate the simulation of different vibration control systems using different earthquake excitations. Conclusion The results obtained reflect that using FO-PID controller improves the performance of active control and can
