摘要: This work applies an active control algorithm, using a macro fiber composite (MFC) to mitigate the unwanted vibrations of rotating blade. The algorithm is second-order oscillator, having positive displacement signal blade for input and suitable force actuate output. oscillator linearly coupled with blade, in mind that their natural frequencies must be vicinity each other. modeled by representing two vibrational directions are coupled. An asymptotic analysis considered understand resulting nonlinear phenomena. Several responses included portray dynamical behavior system under control. From results, we observe asymmetry between blade’s directions. Moreover, verification comparing analytical numerical results.
