...J. Jiang; H. H. Yue; Z. Q. Deng; H. S. Tzou Light-driven photostrictive actuators can induce control actions for wireless non-contact actuation and control of precision structures and systems. Conventional distributed actuators laminated on shells and plates usually only introduce uniform control...

...Mauro Caresta; Nicole Kessissoglou This paper investigates the use of inertial actuators to reduce the sound radiated by a submarine hull under excitation from the propeller. The axial forces from the propeller are tonal at the blade passing frequency. The hull is modeled as a fluid-loaded...

...G. Cazzulani; F. Resta; F. Ripamonti Concrete placing booms are subjected to vibrations that increase mechanical stress and reduce the boom’s working life. The aim of this paper is to develop an active control methodology to suppress boom vibrations using the same actuators that produce the large...

... actuators forced vibration laminated composite plates piezoelectric materials sensors Laminated composite structures are very commonly used in various industries because of their high strength to weight ratio. Many researchers have investigated composite material structures in the past...

... that the adaptive pole placement controllers are noise tolerant, but require high actuator voltages to maintain stability. However, robust pole placement controllers require comparatively small amplitude of control voltage to maintain stability, but are noise sensitive. It was realized that by using...

...S. M. Yang; G. J. Sheu It has been stated that a uniform rotating shaft in the Rayleigh beam model has only a finite number of critical speeds and precession modes. This paper presents a controller design of optimal sensor/actuator location and feedback gain for steady state unbalance response...

...Senthil S. Vel; Brian P. Baillargeon An analytical solution is presented for the static deformation and steady-state vibration of simply supported hybrid cylindrical shells consisting of fiber-reinforced layers with embedded piezoelectric shear sensors and actuators. The piezoelectric shear...

...P. De Man, Graduate Student; A. Franc¸ois, Graduate Student; A. Preumont, Professor, Mem. ASME A SISO control system is built by using a volume displacement sensor and a set of actuators driven in parallel with a single amplifier. The actuators location is optimized to achieve an open-loop transfer...

...Gyo¨rgy Sza´sz and; George T. Flowers For a tuned or symmetrically mistuned bladed disk assembly, several vibration modes are coupled only to the axial dynamics, which forces controllers to rely on an axial actuator. A control strategy based upon deliberately mistuning in a nonsymmetric manner...

...Yuan Shu-Qing,; Xu Qing-Yu,; Zhang Ling Experiments are performed to actively suppress vibration of a flexible four-bar linkage mechanism bonded with piezoelectric materials as sensor and actuator. The control system is built up with computer, A/D and D/A converter, low-pass filter, voltage...

...F. J. Shelley; W. W. Clark The purpose of this two-part work is to apply active mode localization techniques to distributed parameter systems where control actuator and sensor placement is a limiting factor. In this paper, Part 2 of the study, the SVD eigenvector shaping technique examined in Part...
