An optimal fractional order controller for vibration attenuation

Unwanted vibrations may cause severe damage and may endanger the lives of passengers on board of an airplane. In the last years, there has been an increased focus on the study of active vibration techniques. A viable possibility to actively control the vibration of an airplane wing is by using piezoelectric actuators. The paper presents a novel tuning procedure of a fractional order Proportional Derivative controller based on three points of the magnitude Bode diagram. The eloquence of the controller is experimentally validated on an experimental setup consisting of an aluminum beam that replicates an airplane wing.
