This paper demonstrates, from viewpoint of electrical connection, comprehensive investigation of a semi-active vibration suppression method using piezoelectric actuators attached to structures. In our system, piezoelectric actuators are connected to an electric circuit composed of diodes, an inductance, and a selective switch. Our method (LR-Switching) makes better use of counter electromotive force to suppress the vibration, instead of simple dissipation of vibration energy. We use an actual artificial satellite to verify their high damping performance compared to conventional semi-active methods. As a consequence, we demonstrate that our semi-active switching method can suppress the vibration of the real artificial satellite to as much as 50% amplitude reduction. In our experiment, we reveal that the suppression performance depends on how multiple piezoelectric transducers are connected, namely, their series or parallel connection. We draw two major conclusions from theoretical analyses and experiment, for contracting effective semi-active controller using piezoelectric actuators. In this paper clearly proves that the performance of the method is the connection of multiple piezoelectric actuators and the their resistances dependent of frequency.
