Research on Dual Axis Synchronous Control System of Gantry EDM Machine Tool

In this paper, a dual axis feed compensation system is proposed for the gantry machine tool. The dual axis servo feed system with two permanent magnet motors is installed in a parallel dual axis control hardware module. In this system, the dual axis synchronous control strategy and control algorithm with model reference adaptive control (MRAC) and fuzzy PID are studied through simulation. By comparing the simulation results, the MRAC is used as the position loop controller and the fuzzy PID is carried out as the cross coupling compensator control algorithm, which can better improve the system dynamic compensation performance in tracking and synchronization control effect. At the same time, in the control module, FPGA is adopted as the main control chip to realize the dual axis synchronous control algorithm, and the correctness of the results is verified by experiments.
