The invention provides a synchronization control method used for a space optical remote sensor servo system. Position servo commands of a main shaft scanning system and a slave shaft scanning system are designed by utilizing a preset index requirement; a main shaft tracking error controller is designed so that rotating scanning movement control performance of the main shaft system is enabled to meet a preset scanning linearity requirement; a slave shaft tracking error controller is designed so that the closed-loop characteristics of the slave shaft tracking error controller are enabled to be identical to those of the main shaft tracking error controller; and a synchronization error controller is designed so that the stable 0 tracking command of the two-shaft servo system is enabled to be stable, thetaxk is added at the output end of the synchronization error controller and output of the main shaft tracking error controller is subtracted so that a synchronization control closed loop is formed, and synchronization control of the space optical remote sensor two-shaft servo system is completed. Compared with master command reference type synchronization and master-slave reference type synchronization, two-shaft synchronization movement precision is greatly enhanced by the method without influencing movement tracks of a main rotating system.
