A feedback control upon nonlinear thermocapillary convections in a half-zone liquid bridge of a high Prandtl number fluid was conducted. In the liquid bridge, the convection changes from two-dimensional steady flow to three-dimensional oscillatory one at a critical temperature difference. The feedback control was realized by locally modifying the free surface temperature using local temperature measured at different positions. The present study aims to develop a new control scheme by taking spatiotemporal azimuthal distribution of temperature fluctuation into account. The performance of the control was evaluated with amplitude of the surface temperature with and without control. The behavior of the present controlled system was compared with that of our previous one on the spectral analysis. The new control scheme achieved significant attenuation of the temperature oscillation compared with the previous one for high Marangoni number region.
