The present application discloses a platform leveling control method, including: acquiring the white light interference fringe pattern of the sample under test, extracting the white light interference fringe pattern according to the white light interference fringe pattern; obtaining the tilt of the measured sample according to the white light interference fringe pattern The orientation angle and the yaw angle; calculate the offset displacement parameter of the platform according to the orientation angle and the yaw angle, and adjust the driving device of the platform according to the offset displacement parameter. The application can calculate the displacement offset feedback of the platform according to the white light interference fringe pattern, and control the driving device of the platform to automatically level the platform, which can replace manual leveling of the platform.

The embodiment of the invention provides a yaw control method and device for a wind generating set, electronic equipment and a storage medium, and belongs to the technical field of control. The method comprises the steps that yaw actions of a draught fan are discretized, an N-way tree about the yaw actions of multiple step lengths is generated, branch sequences meeting sequence invalidation conditions in the N-way tree are cut off, the pruned N-way tree is obtained, and the N-way tree is subjected to yaw control; and according to a set control step length, selecting a control action solution matched with the control step length from the trimmed N-way tree as a target action solution, calculating a control sequence corresponding to each target action solution, and selecting an optimal control sequence from a plurality of control sequences, thereby greatly reducing a searchable solution space of the optimal control sequence, and improving the accuracy of the optimal control sequence. Therefore, the calculation amount and calculation resources in the optimal control sequence acquisition process can be reduced.

The invention discloses a crosswind yaw control method and system for a wind generating set and related components. The crosswind yaw control method comprises the following steps that when the rotating speed of an impeller exceeds a preset rotating speed limit value, whether blades are stuck or not is judged; if yes, a crosswind yaw instruction is generated so that the impeller can be controlled to swing by a preset angle in the preset direction. According to the crosswind yaw control method for the wind generating set, crosswind yaw operation is conducted under the conditions that the wind generating set is over-speeding and the blades are stuck, the impeller of the wind generating set is prevented from directly facing the wind direction, then the situation that the rotating speed of thewind generating set is continuously increased in emergency is avoided, and safety is improved.
