In this study, three types of surface motion of smart skins were proposed and used to control the Tollmien-Schlichting(T-S) wave in the laminar boundary layer of a plate. These three types of motion are standing transverse wave (with out-of-plane displacement), progressive transverse wave and standing longitudinal wave (with in-plane displacement). The length of smart skin was set to 1,2 or 3 cycles of waveform. Numerical simulation was performed on the dependence of control effect on the amplitude and the phase of the surface motion, and the number of waveform was investigated.
