中文摘要 |
本文探讨以Petri网为模型的离散事件系统(DES)的某种禁止状态避免问题,提出了以Petri网N为基网,设计具有外部输入位置Petri网(PNIP),对N进行协调反馈控制的方法。由N现行状态反馈决定的PNIP的控制状态,既保证N避免禁止状态,又使N具有最大自由度。 |
英文摘要 |
In this paper, the problem of some kinds of forbidden states avoidance in discrete event systems modeled by Petri nets is discused. A method, that designs a petri net with external input places(PNIP)which is based on Petri nets N and implements feedback control logic of coordination on N, is presented. The control state of PNIP decided by N’s current state ensures that N avoides forbidden states and has permissive maximally freedom. |
