This steering control device is configured to execute offset amount calculation processing, offset compensation processing, and offset reduction processing. The offset amount calculation processing is processing for calculating an offset amount which is a difference equivalent amount between a target turning equivalent angle and an actual turning equivalent angle with satisfaction of a predetermined condition as a trigger. The offset compensation processing is processing for correcting the target turning equivalent angle by an offset correction amount corresponding to the offset amount. The predetermined condition includes a plurality of types of conditions. The offset amount calculation processing and the offset compensation processing are provided separately for each of the plurality of types of conditions. The offset reduction processing is processing for reducing the magnitude of the offset correction amount, and when two or more mutually different offset compensation processing instances are executed, includes cooperative processing for cooperatively setting a reduction rate of the offset correction amount used in the two or more offset compensation processing instances.

This steering control device is configured to execute offset amount calculation processing, offset compensation processing, and offset reduction processing. The offset amount calculation processing is processing for calculating an offset amount which is a difference equivalent amount between a target turning equivalent angle and an actual turning equivalent angle. The offset compensation processing is processing for correcting the target turning equivalent angle by an offset correction amount corresponding to the offset amount. The offset reduction processing is for reducing the magnitude of the offset correction amount, and is processing for, when the magnitude of the offset correction amount is reduced to a predetermined value or less, changing a reduction rate according to the magnitude of the offset correction amount, under a condition in which the reduction rate of the magnitude of the offset amount when the magnitude of the offset correction amount is large is equal to or greater than the reduction rate when the magnitude of the offset correction amount is small.

This invention discloses a method, system, and cold-hardened strip steel with a sheet shape stability of 0.1*1500mm. The method includes: modifying the roll profile and rolling passes of the single stand based on the sheet shape defects formed after the test product is rolled on a single stand; adjusting the reduction rate of each pass based on the sheet shape defects and rolling parameters of the test product; and after determining the reduction rate of the last pass, proportionally reducing the reduction rate of each preceding pass; when the test product has curled or wrinkled sheet shape defects, measuring and adjusting the levelness of the roll mandrel to keep it below a set levelness threshold; and when the levelness of the roll mandrel is kept below the set levelness threshold, rolling the target product according to the modified roll profile, rolling passes, and reduction rate to obtain the cold-hardened strip steel with an extreme thinness of 0.1*1500mm.

This application provides a data processing method, apparatus, web client device, storage medium, and computer program product. The method includes: starting a first predetermined number of task threads by a main thread, and assigning the first predetermined number of tasks to be executed in a task group to the first predetermined number of task threads for execution, thereby obtaining a first execution completion time; performing a first operation and a second operation by the main thread to obtain a second execution completion time; re-executing the first operation and the second operation if the reduction rate of the execution completion time is greater than or equal to a predetermined threshold; and / or repeating the second operation if the reduction rate of the execution completion time is less than the predetermined threshold, until all tasks to be executed in the task group are completed.

The application discloses a cold-rolled strip surface quality control method, device, medium and electronic equipment. The method comprises the following steps: acquiring the rolling speed of a fourth rack, judging the rolling speed, and the fourth rack is used for finish rolling of the cold-rolled strip; if the rolling speed of the fourth rack is greater than the expected speed, reducing the corresponding reduction rates of a first rack, a second rack and a third rack, and increasing the corresponding reduction rate of a fifth rack, the first rack, the second rack and the third rack are used for rough rolling of the cold-rolled strip, and the fifth rack is used for rough rolling of the cold-rolled strip; after reducing the corresponding reduction rates of the first rack, the second rack and the third rack and increasing the corresponding reduction rate of the fifth rack, adjusting the corresponding reduction rate of the fourth rack to improve the surface quality of the cold-rolled strip. The technical scheme provided by the application can improve the surface quality of the cold-rolled strip.
