Research on Control Algorithm of Up Package Based on Digital Twin
In order to improve the control performance of up-package machine,a digital twin control method is pro-posed.First,by analyzing the dynamic model and kinematic model of the package,the time and space constraints of efficient package supply are obtained.Then,a digital twin control framework is constructed.Three-dimensional models of up-package machine,package,and sorting machines to build a dynamic model of the system.Furthermore,parame-ters of up-package machines,package,and sorting machines are used as inputs,and the loading time is used as a constraint to solve the running speed of the conveyor belt in the acceleration and deceleration sections,thereby achieving precise control of the packaging time and location.The experimental results show the effectiveness of the digital twin control method.And the initial position of the package is the main factor affecting the landing point of the package.The friction coefficient between the package and the conveyor belt,the upper package position,and the gap between sections are the main factors affecting the control performance.
