＜正＞In this study,a PI-like fuzzy logic controller is designed to accommodate the nonlinear behaviors in the constant tip-deflection systems for contact mode *** exploiting the fuzzy logic structure of the controller,heuristic knowledge is incorporated and results in a non-linear controller with improved transient performance over traditional PI *** the proposed controller allows the cantilever tip to track sample surface rapidly and *** rapid tracking response facilitates us to observe high aspect ratio micro structure accurately and ***, continuously manual gain tuning by trial and error in commercial AFMs is *** final,the proposed PI-like fuzzy controller shows better performance than traditional PI controllers.

Atmospheric Pressure Plasma Processing of Fused Silica in Different Discharge modes

引用

Plasma Science and Technology 2015年第7期17卷 567-573页

作者：李娜辛强张鹏王波 Center for Precision Engineering Harbin Institute of Technology

One of the major advantages of utilizing atmospheric pressure plasma processing （APPP） technology to fabricate ultra-precision optics is that there is no subsurface damage during the process. In APPP, the removal footprint and removal rate are critical to the capability and efficiency of the figuring of the optical surface. In this paper, an atmospheric plasma torch, which can work in both remote mode and contact mode, is presented. The footprints and the removal rates of both modes are compared by profilometer measurements. The influences of process recipes and substrate thickness for both modes are investigated through a series of experiments. When the substrate is thinner than 12 mm, the removal rate in contact mode is higher. However, the removal rate and width of the footprint decrease dramatically as the substrate thickness increases in contact mode.

It is found that a pitch-catch signal was more sensitive than normal incidence backwall echo of longitudinal wave to subtle flaw conditions in the composites(damages,fiber orientation,low level porosity,ply waviness,and cracks).The depth of the sampling volume where the pitch-catch signal came from was relatively shallow with the head-to-head miniature Rayleigh probes,but the depth can be increased by increasing the separation distance of the transmitting and
