Design of Tension Control System of Silicon Rod Wire Cutter

Aiming at the cutting process of silicon rod, a tension control system is designed on the basis of wire cutting technology, the development status of silicon rod cutting technology is introduced, the principle of tension generation is introduced, and two kinds of tension compensation structures (tension hammer structure and tension pendulum structure) are modeled and analyzed. The whole tension control system including spindle and tension compensation servo is modeled, the control system schematic is given, and the performance of the system is tested by Matlab simulation. The steady-state performance of the system under tension shock and tension fluctuation is verified, and the fuzzy PID controller is designed for tension control, which enhances the robustness of the system and improves the cutting efficiency and cutting quality.
