Sub-mirror wind-induced vibration control method and device for improving condensation efficiency of heliostat

The invention relates to the technical field of heliostat control, in particular to a sub-mirror wind-induced vibration control method and device for improving the condensation efficiency of a heliostat, and the method comprises the steps: S1, calculating the azimuth coordinates of the sun and the angle of incident light of the sun according to the date and latitude; s2, calculating according to the sun azimuth coordinate, the heliostat surface center coordinate and the heat collection tower target area center coordinate to obtain the ideal pitch angle and azimuth angle of the whole heliostat; s3, calculating ideal pitch angles and azimuth angles of the sub-mirrors in the upper row and the lower row according to the center coordinates of the mirror surfaces; and S4, according to a calculation result, adjusting a unified angle of pitch angles of the single-row sub-mirrors, and then respectively adjusting azimuth angles of all the sub-mirrors in the upper row and the lower row. According to the method, the over
