A high-precision synchronous position information calibration system and method based on a servo mechanism

Abstract

The invention discloses a high-precision synchronous position information calibration system and method based on a servo mechanism, which overcomes the defect of insufficient synchronization accuracy of position information between a tested product and a servo mechanism in the prior art, and adopts a computer to realize the synchronization of the servo mechanism. The output function of high-precision synchronous position information uses the external pulse triggering and latching functions corresponding to the dual-core of the high-precision counting board, and adopts the method of split-core processing to simplify the servo control system and realize the position information between the servo mechanism and the product under test. High-precision synchronization improves calibration efficiency.

Description

technical field [0001] The invention relates to the technical field of servo mechanisms, in particular to a high-precision synchronous position information calibration system and method based on a servo mechanism. Background technique [0002] In the application of high-precision servo control system, in order to synchronize the position information of the servo mechanism and the product under test and improve the system performance of the product under test, the output of the synchronized position information of the servo mechanism is essential. [0003] In the prior art, in the field of high-precision servo control, there is currently no national standard for realizing the output of synchronous position information, such as figure 1 As shown, based on the synchronous position information output method in the prior art, the common test principle of the synchronous position information calibration system based on the servo mechanism is: the product under test is placed on th...
