The gantry type motion platform based on permanent magnet linear motor (PMLM) is widely used in the field of chip packaging. Due to the mechanical coupling of the beam between the two axes, it is difficult to achieve fast response and precise synchronization of the system. Taking the gantry motion platform as the research object, based on the threeloop servo control system including current loop, speed loop and position loop, a fuzzy feedforwardbased control strategy was proposed, and the crosscoupling synchronization algorithm was adopted to achieve fast synchronous performance of the system. The traditional PID synchronization control and fuzzy feedforwardbased synchronization control algorithm were compared and analyzed. The simulation results show that the rise time of step response under the fuzzy feedforward control is 485 ms, which is 65% shorter than the traditional PID control; the crosscoupling synchronization algorithm ensures positioning precision, so the system has good synchronous following performance and strong antiinterference ability, which basically meets the requirements of highspeed and highprecision chip packaging.
