The problem of the synchronous drive for gantry-moving milling machines is researched in the paper. Two same linear motors are used as drive mechanisms of synchronous feed. The dynamic compensated method is adopted, effectively limiting the falling of the system's performance which is produced by the changing of the equivalent inertia. At the same time, puting the fuzzy PID controller in the velocity loop of the system, effectively applying that fuzzy control is independent on the plant model and has the characteristic of the control fast and stronger robustness. The synchronous control precision is enhanced. The simulation results show that the performance of the system is better and the fast synchronous feed is implemented.
