%X 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.
