Abstract
This paper proposes two design methods of piezoelectric dampers. One is based on the fixed-point theory by which the parameters of piezoelectric dampers that suppress the accelerance are optimized. The other is based on the H∞ static output feedback control theory. Since minimizing H∞ norm of the system implies suppressing the magnitude of the frequency response of the system, this method is applied to the design of piezoelectric dampers. The effectiveness of the piezoelectric damper designed by the H∞ control theory method control theory is examined compared with that designed by the fixed-point theory.
