摘要
应用混合随机Petri网对神光III控制系统的故障进行了建模,并应用Visobj Net对建立的故障模型进行了仿真分析。网络化控制系统是一个离散和连续相结合的混合动态系统,具有动态、并发及同步等特征;神光III控制系统就是网络化控制技术在武器装备上的一个典型应用;对于复杂系统的建模和分析,Petri网是一个非常有效的工具。Petri网已经被证明是离散事件或异步系统很好的建模和分析工具,混合随机Petri网是Petri网的一个扩展,具有强大的建模功能。仿真结果表明,所建立的模型是正确的。
Networked control system, characterized by dynamics, concurrence and synchronization, is a hybrid dynamic system involving discrete and continuous behaviors. Petri net is a powerful technique widely used in modeling and analysis of complex systems. Shenguang Ⅲ control system is a typical application of networked control technology in weaponry arming. Petri net is an excellent modeling and analysis tool for discrete event or asynchronous systems. Hybrid stochastic Petri net having powerfully modeling ability is an expanse of Petri net. Fault model of Shenguang III control system is given based on hybrid stochastic Pertri nets, and simulate with VisObjNet.
