Embodiment Construction
[0052] Such as Figure 6 Shown: the position control method based on the sliding distance of the invention of the present invention comprises the following steps:
[0053] 1. New setting value Wo issued: This is a pulse trigger signal, indicating that the process machine has issued a width value different from the previous one, and the device needs to be re-adjusted.
[0054] 2. Situation 1: X
[0055] 3. Situation 2: X>Wo: If the current position is smaller than the target position value, it indicates that it needs to move in the direction of width reduction, and then issue t...

This invention relates to a three-point type position control method based on slide distance. Wherein, setting the value variation to divide the control process into two stages: first, comparing the new set value Wo with real width, modifying it as Wo+2So or Wo-2So (or more large for real condition); second, when the error more than 2So, taking position control by original value. By This invention, the probability that the number of rotation and counter-rotation is within 3 can be more than 80%.
Description
technical field [0001] The invention relates to a position control method of a mobile device driven by a three-phase AC asynchronous motor, in particular to a position control method based on a sliding (pre-stop) distance. Background technique [0002] For equipment driven by three-phase AC asynchronous motors, such as blast furnace charging trolleys, side guide plates in front of rolling mills, etc., by controlling the forward and reverse rotation of the AC motor, the mechanical transmission mechanism converts the rotation of the motor into a change in displacement. Feedback, compared with a set position to achieve position control of these mobile devices. [0003] Such as figure 1 Shown: The existing hot rolling rough rolling production line is composed of four stands, each stand is composed of side guide plate 4 (SideGuide), vertical roll 1 (Edger), horizontal roll 3 (Rougher), and the side guide plate is used to guide The slab enters and exits the frame along the cente...
