| 英文摘要 |
| In order to realize the formal design of programmable logic controllers (PLC), a novel type of Petri nets
that can perform perceptions and executions is defined, which is called a parallel Petri net. By mapping input and output
variables to place nodes, a general approach is presented to design a PLC’s Petri net, and a dynamic evolution algorithm
is established. By programs designed in C language and TwinCAT, the Petri net can parallelly evolve with a plant to
be controlled, and consequently ensures the control specifications. The method provided in this work could serve as an
effective tool for applications of parallel systems in PLC projects. Consequently, development cycles of control code can
be shortened and it is eased to the reuse PLC programs. |
