摘　　要：针对柔性制造系统控制方案设计过程中逻辑复杂、调试周期长、调试成本高等问题,提出一种基于可试验数字孪生体的虚拟调试方法。该方法以分层的方式建立物理系统的孪生模型,基于离散事件系统规范的扩展形式构建设备层、单元层、系统层3层的逻辑模型,通过仿真对逻辑模型进行重复验证与修改。建立了逻辑模型到PLC程序的映射规则,实现了PLC程序的快速设计。最后,以某柔性制造系统为例,详细演示了逻辑建模过程及PLC程序的设计,验证了所提方法的可行性和有效性。Aiming at problems of complicated logic,long commissioning cycle and high commissioning cost in the design process of flexible manufacturing system control scheme,a virtual commissioning method based on experimentable digital twin was proposed.This method established the twin model of physical system in a layered manner,and established a three-layer logic model of equipment layer,unit layer,and system layer based on the extended form of discrete event system specification.The logic model was repeatedly verified and modified through simulation.The mapping rule from logic model to PLC program was established to realize the rapid design of PLC program.Finally,taking a FMS as an example,the process of logic modeling and PLC program design were demonstrated in detail.The feasibility and effectiveness of the proposed method were verified.
