Active vibration control of a flexible beam using system identification and controller tuning by evolutionary algorithm

This paper presents a new approach of proportional-integral-derivative (PID) controller tuning via an evolutionary algorithm that optimally suppresses the vibration of a flexible beam system using a piezoelectric actuator. The system's dynamic model is identified based on autoregression with ex...
