AI Technical Summary
Existing multi-point temperature control systems suffer from temperature overshoot, oscillation, and excessively long steady-state settling time in high-density sample point arrays. Furthermore, during high-speed dynamic scanning, there is a timing deviation between the laser control signal and the mechanical response of the galvanometer, resulting in insufficient energy projection accuracy.
A thermal diffusion coupling model containing a spatial coupling attenuation matrix and a time transmission lag matrix is constructed. Historical time-domain convolution calculation is performed using energy-managed queue data. Dynamic priority ranking is generated by combining energy deficit and mechanical jump cost. Beam projection control is performed using a galvanometer dynamics model to achieve hardware delay matching between laser control signal and galvanometer position signal.
It solves the problem of temperature overshoot and oscillation caused by thermal diffusion coupling effect, optimizes the steady-state accuracy of multi-target temperature field and the time accuracy of energy projection, and improves the steady-state accuracy of multi-point collaborative control and the efficiency of light energy resource allocation.
