中文摘要
      提出了一种用于可重构制造单元故障恢复的策略与方法, 允许故障发生时, 通过对用于正常操作控制的Petri网形式的监督控制器进行局部、临时性的修改, 实现故障的恢复. 首先, 提出改进的网重写系统, 可用于动态改变Petri网模型结构. 然后,提出了基于改进的网重写系统的故障恢复方法, 其中改进的网重写系统用于操作、引导Petri网监督控制器由错误状态进入正确状态. 故障恢复后监督控制器的结构与期望属性维持不变. 最后, 以实例演示了该故障恢复方法的应用, 证实了方法的有效性.
英文摘要
      The strategy and method for recovering an error occurring in a reconfigurable manufacturing cell(RMC) are proposed by a partial and temporary modification on the supervisor in Petri net(PN) formalism for normal operation control. Firstly, the improved net rewriting system (INRS) is presented that offers a direct way to dynamical structural changes in a PN model. Subsequently, an INRS-based error recovery method is presented, where the INRS is used to operate a PN supervisor and induct it into a correct state from the error one. After error recovery the structure and expected properties of a resulting supervisors is naturally preserved. Finally, with help of an example, the error recovery method presented is illustrated and the result shows the validity of the method.
