Takao Fujii, Taro Tsujino, Tatsuya Sugano, H. Kitayama, M. Hayahi, N. Shikano · 2005
Designs a control system for shaping the low frequency characteristics of a new type of hydraulic speaker, so as to-make a louder sound at low frequencies than the usual type of speaker. In this design, the authors use H/sub /spl infin// control design method, which is capable of treating both frequency shaping and robust stabilization. The authors also illustrate the validity of the resulting controller by showing some experimental results.
