【摘要】 城市道路线控系统是一个离散和连续相结合的混合系统,具有动态、并发及同步特征,Petri网能很好地描述这些动态行为。因此,本文进行了线控系统的Petri网建模及其控制研究:基于模块化建模思想建立了混合Petri网相位模块;相位模块着色后组建了线控系统模型,模型直观、简单易读;将模糊理论嵌入Petri网模型中,运用模糊规则定义了一些变迁,使线控系统Petri网模型适于配时设计。更多还原

【Abstract】 Urban artery system,which is characterized by dynamic,concurrence and synchronization,is a hybrid dynamic system involving discrete and continuous behaviors.The dynamic actions of the urban artery system can be modeled through Petri nets.Therefore,modeling and control of the urban artery system based on Petri nets are discussed in this paper.First,a phase module is modeled using hybrid Petri nets according to modularization methods.Then,a distinct and readable model of the urban artery system is presented after coloring the phase module.Moreover,to scheme signal parameter,fuzzy theory is embedded into Petri nets by using fuzzy rules to define some transitions of Petri nets.更多还原
