混合系统的面向对象仿真

Object-Oriented Simulation for Hybrid Systems

提出了一种新的混合系统自动机模型。该模型把混合系统看作是由系统行为模式集、连续状态空间、外部输入集、演化函数集、转移函数集、外部输入函数集等组成的六元组,对混合系统的行为具有很强的描述能力。在此基础上,利用面向对象思想,把混合系统看作由实体对象、时序对象和界面对象组合而成的对象,建立了混合系统的面向对象仿真模型,并讨论了其仿真逻辑。这一模型为混合系统的仿真提供了通用的框架。

In this paper a new automata model for hybrid systems is put forward. In this model,the hybrid system is a hexadic structure which consists of a finite set of behavior modes,continuous state space,a finite set of exterior state variables,a set of evolvement functions,a set of transfer functions and a set of exterior input functions. The model is strong in the description of the system behaviors. Based on the model and object-oriented methodology and taking the hybrid system as a combination of entity object,sequence object and interface object,an object-oriented simulation model is built and simulation logic is discussed. The simulation model provides a general frame for hybrid system simulation.
