適応追従制御法による機械振動の能動的制御 : 特に旋削加工系のびびり振動に関して Active Control of Mechanical Vibrations Using an Adaptive Control Technique : Especially of Chattered Vibrations in a Turning Cutting Process 川辺, 尚志 カワベ, ヒサシ 西尾, 洋彦 ニシオ, ヒロヒコ 池田, 工 イケダ, タクミ Kawabe, Hisashi Nishio, Hirohiko Ikeda, Takumi active control self-excited chatter turning cutting process adaptive tracking control robustness Merritt's model tracking error application/pdf Active control effects of self-excited chatter occurring in a turning process have been investigated from the simulation aspects, by utilizing Merritt's modeling method for a machine strucure and the adaptive tracking control techniques developed by Ambrosino, et al. The followings have been obtained. The delay of the control start time, at which the total system is changed from an open loop system into a closed one, hardly affects the vibration control effects, while the larger size of the error sphere (llνll =p) lowers the adaptive tracking performance due to increasing unstable regions. There is also an optimal δopt to minimize the tracking errors in the continuous function cont(ν) =ν/ (llνll +δ). Furthermore, it is found that the control scheme adopted here shows the better robustness against a fairly largeness of parameter variation and modeling error, as compared with that of the LQ control system. departmental bulletin paper 広島工業大学 1993 VoR application/pdf 広島工業大学研究紀要 27 127 136 AN0021271X 03851672 https://it-hiroshima.repo.nii.ac.jp/record/532/files/kenkyukiyo27127.pdf https://it-hiroshima.repo.nii.ac.jp/records/532 jpn
