摘　　要：自动制造系统中关于死锁问题的研究非常热门,而人们为了分析方便,也总假设资源永远不会损坏,但是资源损坏在实际生产中是非常普遍的情况,不能忽视。利用Petri网对自动制造系统进行建模和分析,重点解决受控系统的稳健性控制问题,并由此提出稳健性提升算法。该算法利用预测控制技术,动态规划后续加工路径,从而保证系统不会阻塞在该故障资源处,或者不使用该故障资源的其他进程能够正常进行加工。The research of deadlock problem in automatic manufacturing system is very popular.In order to facilitate the analysis,people always assume that resources will never be damaged.But the damage of resources in the actual production is very common situation,and can not be ignored.Petri net was used to model and analyze the automatic manufacturing system to solve the robustness control problem of the controlled system in the paper,and the robustness algorithm was proposed.Using the predictive control technology and dynamic path planning the subsequent processes,the algorithm ensured system will not to be blocked in the fault resources place,or can be processed properly without using the other processes of the fault resources.
