| 摘 要： | 为了对混合系统进行有效地建模,提出了一种扩展的面向对象混合Petri网(EOHPN)建模方法.针对混合系统的复杂性,在EOHPN模型中融入了面向对象的抽象机制,例如封装和类定义.为了结合混合系统的连续部分和离散部分,减少混合系统的复杂性,引入混合Petri网并用面向对象建模技术作了扩展.在定义EOHPN模型的基础上,拓展了对象模型.最后,用实例描述了基于EOHPN的混合系统建模过程,同时验证了EOHPN模型在处理复杂混合系统建模时是有效的.

| Abstract: | In order to model effectively hybrid systems,a new modeling method of extended Petri nets,which is called extended object-orient hybrid Petri net (EOHPN),is proposed.To deal with the complexity of hybrid systems, object-oriented abstraction mechanisms such as encapsulation and classifications are merged into EOHPN models.To combine the continuous part and discrete part of hybrid systems and to reduce the complexity of hybrid systems,a hybrid Petri net is introduced and extended with object-oriented modeling technology.Development of object models is suggested on the basis of the defined EOHPN.Finally, an application-oriented case is presented to illustrate that how the proposed EOHPN is used to model hybrid systems.The resulting model validates that the EOHPNs can deal with the modeling complexity of hybrid systems. |
