Abstract: Provided are a dual-AGV collaborative carrying control system and method, which relate to the field of smart logistics carrying robots. The method is mainly for meeting the conveying requirements of large components, specifically of objects which have relatively large dimensions in the length direction, and is a combination of a path tracking method and a navigator-following method. By using a collaborative planning model that has a three-layer topological structure, the formation deviation under a dual-AGV navigator-following strategy is combined with the path deviation under path tracking to obtain a navigator-following and path tracking-based kinematic control model, and a time-domain rolling predictive control-based discrete control model is used to optimize the kinematic control model, thereby achieving the stable and reliable path tracking and collaborative carrying of the dual-AGV system.
