Multi-tone Adaptive Vibration Isolation of Engineering Stru~ures

چکیده
We present a multi-tone narrow band tracking control algorithm to isotate periodic disturbances from engineering structures. Conditions for fast convergence of control parameters are discussed. It is shown that the choice of appropriate tap delay time and number of taps is important in achieving good convergence. We implemented the algorithm in a digitat computer to attenuate a two-tone periodic disturbance from a flexible aluminum truss structure. Experimental results showed that disturbance rejection of over 25 dB was achieved.

Vibration Suppression of Fuel Sloshing using Subband Adaptive Filtering (RESEARCH NOTE)
One of the main vibration problems of aerospace vehicles with liquid fuel propulsion system is fuel sloshing. This phenomenon is a low frequency vibrational challenge which can affect the motion of the vehicle and degrade the stability of the main control system. In this regards, the motion of the liquid will be very critical when the frequency of the sloshing is very close to the frequencies o...

متن کاملAdaptive Tunable Vibration Absorber using Shape Memory Alloy
This study presents a new approach to control the nonlinear dynamics of an adaptive absorber using shape memory alloy (SMA) element. Shape memory alloys are classified as smart materials that can remember their original shape after deformation. Stress and temperature-induced phase transformations are two typical behaviors of shape memory alloys. Changing the stiffness associated with phase tran...
