Dalam kertas ini, kaedah penyesuaian untuk kawalan aktif keamatan getaran dalam domain frekuensi dicadangkan. Dalam kaedah ini, keamatan getaran diperhatikan dengan kaedah 4-sensor, dan pekali penapis FIR adaptif untuk kawalan aktif diperbaharui dengan algoritma Block Filtered-X LMS dalam domain frekuensi. Satu eksperimen dengan kaedah yang dicadangkan dilakukan pada model mudah. Hasilnya, kaedah yang dicadangkan memberikan pengecilan intensiti getaran yang lebih besar daripada kaedah konvensional di kawasan frekuensi tinggi. Pengecilan keseluruhan dalam keamatan getaran di kawasan frekuensi itu ialah 14.1 dB dengan kaedah yang dicadangkan, manakala ia adalah 7.0 dB dengan kaedah konvensional. Di kawasan frekuensi yang lebih rendah, pengurangan dalam keamatan getaran oleh kaedah yang dicadangkan adalah kira-kira setara dengan yang diperolehi oleh kaedah konvensional. Peningkatan juga boleh dicapai di sana dengan menetapkan selang antara penderia ralat dengan betul.

Abstract: In this paper, an adaptive method for active control of vibration intensity in the frequency domain is proposed. In this method, vibration intensity is observed with the 4-sensor method, and the coefficients of an adaptive FIR filter for the active control is renewed with the Block Filtered-X LMS algorithm in the frequency domain. An experiment with the proposed method is performed on a simple model. As a result, the proposed method gives larger attenuation of vibration intensity than the conventional method in the high frequency region. The overall attenuation in vibration intensity in that frequency region is 14.1 dB with the proposed method, while it is 7.0 dB with the conventional method. In the lower frequency region, the reduction in vibration intensity by the proposed method is roughly equivalent to that obtained by the conventional method. An improvement may also be achieved there by setting the intervals between error sensors properly.
