A novel self-sensing method using piezoelectric actuators for semi-active vibration suppression is proposed. By using extended system equations, this self-sensing method can be implemented with a Kalman filter instead of the conventional bridge circuit technique. This method is so advanced that it can be applied to multiple-degree-of-freedom (MDOF) structures with multiple piezoelectric actuators. A numerical simulation demonstrated that the self-sensing method works well on a truss structure and has significant robustness against parameter variations. Experimental results also confirmed that the self-sensing method suppresses not only single-mode vibrations but also complicated multiple-mode vibrations.
