摘要
为了解决多能源混合动力汽车（HEV）中能量控制系统在建模时不能完全描述连续动态事件和离散动态事件等问题,基于切换控制系统理论,建立能量控制系统数学模型,根据车辆运行工况,提出了6种工作模式,应用切换系统理论中8元组定义模式描述能量控制系统,采用逻辑判断方法,建立切换规则、系统跳变关系和各工作模式之间转换的映射集.仿真结果与ADVISOR软件中混合动力汽车的基本控制策略得到的结果相比,SOC值始终工作在最优工作区域65%~75%,碳氢化合物（HC）、一氧化碳（CO）、氮氧化合物（NOx）和微粒（PM）的排放量各自减小了17.1%,21.5%,7.3%和2.7%.结果表明将切换系统理论应用到HEV的能量控制系统中切实可行.
To solve the problem that continuous variable dynamic system and discrete event dynamic system for hybrid electric vehicle（HEV） can not be fully described by energy control system during modeling,a new mathematic model was developed based on switched system theory.According to various operating modes,six modes were proposed,and an eight-tuple representation was presented to define energy control system.Switching rules,jumping conditions and mapping sets of switching among all operating modes were established by logical judgement.Compared simulation results with ADVISOR default values from basic control strategy method,it is found that SOC value is always at optimal range of 65%-75%,and the emissions of HC,CO,NOx and PM were reduced by 17.1%,21.5%,7.3% and 2.7%,respectively.Simulation results show that switched system can be effectively applied to energy control system of HEV.
