Improving the accuracy of the drive screw pressure.
The question of the use of two-channel iterative systems to improve the accuracy of the drive pressure screws is considered. It is shown that the use of an iterative drive allows you to make the most of the dynamic properties of individual channels and significantly improve the accuracy of the system. The influence of the parameters of the second channel on the dynamic properties of a two-channel drive is studied in the case when each channel is tuned to a modular optimum. The dependences obtained allow us to choose the determining parameters of the system for which the specified quality of the transient process is achieved.
