抄録
As a future high-precision space structure system, smart structure systems which measure and correct their shape on orbit have been studied. In the smart structure systems piezoelectric ceramics are often used as an actuator. To correct and retain the shape of the structure, electric voltage must be applied continuously. To reduce the amount of electricity usage, a new control method was proposed, where the fact that strain of the piezoelectric ceramics remains without applied voltage after a pulsed voltage input was utilized effectively. In the previous study, the feasibility of the proposed method had been verified for a piezoelectric ceramic plate and a beam with the piezoelectric ceramic plate bonded. The result had shown that the strain of the piezoelectric ceramic plate and the tip displacement of the beam had remained after the pulse, although the beam had vibrated. In this study the strain response for the pulsed voltage was observed for various types of piezoelectric ceramic plates including hard type and soft type, and the vibration of the beam was suppressed by applying a feedback control or a trigonometric shaped pulse input.
