Riassunto
The main objective of this thesis is the progression of experimental studies of Macro Fiber Composite (MFC) piezoelectric actuators embedded on compos- ite laminates, up to the development of an hysteresis compensation system and his implementation on self-shaping control. A test campaign has been carried out to characterize the hysteresis phenomenon in order to develop an experimentally- validated MATLAB-Simulink model of the MFC specimen. Then, the model has been used to design the hysteresis compensation architecture and define new con- trol laws parameters for the self-shaping closed-loop control. Stability and perfor- mance characteristics of the response in both low and high frequency ranges has been investigated as well as limit cycle condition has been portrayed and a com- pensation strategy has been defined. The whole control design activity has been experimentally-validated by developing specific software in the LabVIEW environ- ment and performing an extensive test campaign on the closed-loop system at the fly-by-wire laboratory of Dipartimento di Ingegneria Civile ed Industriale (DICI) of the Universit ́a di Pisa.
