...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...

...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...

... 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...

...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...
