Aiming at out-sync problem of antenna hydraulic lifting movement due to increasingly weak stiffness of antenna,combined with the characteristic of antenna structure,a new synchronization control scheme based on oil compensation was put forward.Co-simulation technology of mechanical electronic hydraulic system was applied,and the simulation analysis was carried out by constructing co-simulation platform of synchronization;a synchronous control experiment system for oil compensation was set up,and the synchronous performance verification was carried out.The results show that the simulation and experiment results are coincident basically;by using the oil compensation synchronization control system,the synchronization control error of the left and right lifting double cylinder can be controlled within 2 mm,which meets the auto-erecting index requirement of radar antenna.
