Abstract:	In the rapid ammunition feeding system of small caliber artillery, flexible bullet chains will have load perturbations, which will increase the synchronization error of dual motors and lead to the failure of the bullet chain in the transmission during the long stroke ammunition transportation. In order to improve the synchronization accuracy of the rapid ammunition feeding system under load disturbance, the speed controller based on active disturbance control is designed to improve the stability of the ammunition feeding system. At the same time, a cross coupled synchronization controller based on sliding mode control is designed to improve the synchronization accuracy of the ammunition feeding system, and the feasibility of the strategy is verified by establishing a synchronous control model for two motors cross coupled in Simulink. Through comparison tests, the rapid ammunition feeding system with ADRC strategy is more resistant to interference, and the synchronization error of the dual motors is 1 rpm and the position error is 0.5°.The test results verify the effectiveness of the proposed method.
