In this paper, a novel approach for fault tolerant control of large-scale manufacturing systems is presented. A specification governor is introduced, which is inspired by the concept of ”reference governor” in feedback control systems. The goal is to modify an infeasible sequence of specifications, which can be used to generate a distributed logic controller, in such a way that the desired product requirements are satisfied in case of faults. The procedure considers redundancies in the manufacturing system and has the capability of keeping the modification of the infeasible specification sequence as less as possible. A modeling process is proposed that automatically adapts fault-free models in form of signal interpreted Petri nets (SIPNs) according to the occurring faults. Based on these faulty models, it is possible to find out which of the natural language specifications in the specification sequence cannot be executed.

在本文中，提出了一种用于大规模制造系统容错控制的新方法。引入了规范调节器，其灵感来自反馈控制系统中的“参考调节器”概念。目标是修改不可行的规范序列，可用于生成分布式逻辑控制器，以便在出现故障时满足所需的产品要求。该程序考虑了制造系统中的冗余，并具有尽可能减少对不可行规范序列的修改的能力。提出了一种建模过程，可根据发生的故障自动采用信号解释 Petri 网 (SIPN) 形式的无故障模型。基于这些有缺陷的模型，
