摘　　要：以中厚板精轧机生产线上全液压十一辊矫直机的控制系统为研究对象,提出一种全新的基于多个嵌入式系统的协同控制架构及控制策略;建立了面向实时任务的预定义模型,变集中计算为分布式计算;实验及运行结果表明,该分布式协同控制系统,可使4个AGC液压缸的随动性能更加可靠,模型运算速度加快,动态跟随误差为0.2mm。Taking the control system of full hydraulic 11 roller leveler in finishing mill product line as the research object, this paper proposed a new cooperative control architecture and its corresponding control strategies based on multi-embedded system. A predefined model for real-time task was established, in which the centralized computing was changed into distributed computing. Experimental results showed that such distributive control system provided the four AGC hydraulic cylinders with excellent serve performances and fast model computation speed with the following error of O. 2mm.
