Projects

Wind turbine acoustic noise
A system for localizing the source of broadband noise from a wind turbine rotor blade has been developed for the use in evaluation noise source and its, control technology.

Active Control of Structure-Born Sound
Radiated structure-born sound emitted from vibrating structures is actively controlled. Minimization of noise is realized by installing distributed-parameter sensors.

Motion Generation by Nonlinear Mechanism
@Study of mechanisms and control method to realize various motion by simple nonlinear mechanisms

Intelligent decentralized control of a flexible distributed-parameter structure
This project concerns the active modal control of a distributed planar structure using point sensors/ actuators designed to replace distributed sensors/actuators,

Microvibration suppression in microfactory base vibration
Finite element analysis schemes are being developed for analysis of radiated acoustic power.
Robust control is being applied to the suppression of microvibrations of a microfactory base.

Control of Nonlinear Vibration for the Realization of a Miniaturized Machine Tool
To miniaturize machine tools in a several cm order, vibrations which detoriorate the cutting accuracy must be suppressed under the operation.
