串行加工系统Petri网控制器的形式化设计方法
A Formal Design Method of Petri Net Controllers for Sequential Manufacturing Systems
-
摘要: 提出了串行加工系统控制描述规格说明的设计方法,研究了规格说明的Petri网语 义.提出了系统Petri网控制器具有活性等希望性质的初始标识的确定算法.这样的Petri网 控制器经编译或算法转换可直接对系统进行实时控制.Abstract: The design method of specifications of the control description for sequential manufacturing systems is presented. The Petri net semantics of the specifications is discussed. The design algorithm has been developed for the initial markings such that the Petri net controlleer has the properties such as liverness, boundedness or safeness, and reversibility. Using the Petri net controller with the desired properties, the real-time control for a practical manufacturing system can be brought into force.
