Tsai, Chun PuChun PuTsaiWEI-CHANG LI2023-04-072023-04-072023-01-01978166549308610846999https://scholars.lib.ntu.edu.tw/handle/123456789/630042This work demonstrates for the first time a micromechanical "attractor exchanger"that allows one to swab operation between the attractors at the high- and low-energy branches that coexist in the hysteresis region of a nonlinear resonator. In particular, instead of using the typical frequency sweeping approach to reach the attractor at the high energy branch, gap-spacing continuation is employed here as an alternative space to transfer the stable operation from lower-energy attractor to the other with the permission of a single-frequency drive. The technique enables a new operation scheme that avoids circuits required for generating frequency sweeping signal for applications based on open-loop operation of nonlinear resonators.Attractor | gap-spacing continuation | parameter sweeping | vibro-impact resonatorconference paper10.1109/MEMS49605.2023.100524202-s2.0-85149825627https://api.elsevier.com/content/abstract/scopus_id/85149825627
