【Abstract】 Based on the improved net rewriting systems(INRS), a method for self-reconfiguration of Petri net (PN) logic controllers for reconfigurable manufacturing systems (RMS) is presented. Firstly, the INRS are developed from the net rewriting system (NRS) and several inherent defects of the NRS are overcome. Subsequently, and INRS based self-reconfiguring method for a Petri net logic controller is presented and the implementation algorithm is designed, which can naturally guarantee the correctness of the resulting Petri net logic controller during reconfiguration and avoid the efforts of complex mathematical analysis and verification. Finally, a reconfigurable manufacturing cell example is used to illustrate the method.更多还原
