This invention discloses a periodic synchronous position interpolation control method and system for servo drives, relating to the field of servo control technology. The method includes: receiving synchronous position commands at a fixed bus cycle and recording their theoretical / actual arrival timestamps; converting the commands into position increments and storing them in a buffer; calculating a buffer saturation index reflecting the supply and demand balance of the command stream in real time; dynamically calculating and smoothly adjusting the next position loop sampling cycle based on this index and its changing trend using a feedback control model; and triggering position loop processing with the adjusted cycle. This invention, by monitoring the command stream status and adaptively adjusting local processing, compensates for the effects of master-slave clock deviation and network jitter, ensuring that the position loop always receives continuous and uniform command input. This achieves high stability and high precision motion control under bus communication, improving the system's anti-interference capability and synchronization performance.

The method includes inputting continuous microscopic images into a target detection model, outputting the target's 2D position, regressing the defocus height and direction from a single frame of local images using a fine-grained ROI-based defocus regression model, directly using the model output to drive a 2D motion platform and a focusing device, fusing the 2D position information of each frame with the corresponding defocus axis information, and incorporating the position information of the previous frame as a priori using a temporal correlation mechanism to achieve continuous correlation of the microscale target in the time dimension, thereby stably reconstructing the target's 3D position and outputting a smooth real-time motion trajectory. This invention achieves real-time 3D localization and stable tracking of microscale targets under single-view bright-field microscopic conditions, ensuring both positioning accuracy and system real-time performance and accuracy.
