摘要: 考虑由具有不可控变迁的受控Petri网建模的DES的控制器综合问题.提出了兼具 DES的逻辑型和结构型二种控制器优点的混合型Petri网控制器:在系统状态的获取和跟踪上具 有结构型控制器的优点,而在控制作用的实施上则具有逻辑型控制器的优点.全文通过实例说明 了混合型Petri网控制器的设计方法.Abstract: This paper addresses the problem of controller synthesis of discrete event systems (DES) modeled by controlled Petri nets (PN) with uncontrollable transitions. The combined PN controller/or DES proposed has both the virtues of the mapping controller and the compiled one, that is, it combines the advantages of the compiled controller in the aspect of obtaining and tracing system state and the mapping controller in the aspect o{ implementing of control action. Examples are used to illustrate the design method of the combined PN controller.
