Aiming at the requirement of high precision and high stability, the closedloop model of the dualdrive servo feed system was established based on the dualdrive synchronous feeding system.The simulation and comparative analysis of the dualdrive feed system were carried out under the two kinds of synchronous control strategies of masterslave and crosscoupling.At the same time, the synchronous control test platform of double closedloop feedback was designed, and the design of synchronous deviation monitoring system was carried out.Dual driving high precision synchronization homing problem was solved via mixed homing way.The doublemotor synchronous driving test was carried out on the test platform, measuring the twoaxis asynchronous error of the worktable at different feed rates.The results show that the synchronization error of the double motor is the largest in the commutation direction.With the increasing of the feed speed, the synchronization error of the doublemotor under the masterslave control is variable and the synchronization error is basically the same under the crosscoupling control.Crosscoupling control of the doublemotor synchronization error is small and with good synchronization performance; mixed homing way can reduce the synchronization error between the two axes, improving synchronous precision.
