摘要
根据能量守恒定律构建系统的功率表达式,对混杂系统进行模式识别与跟踪.首先对混杂系统进行键合图建模,对系统的每个疑似模式构造其诊断键合图模型并推导功率表达式.通过分析诊断键合图产生的残差,判断混杂系统的当前运行模式.最后利用20-sim键合图仿真软件进行仿真实验,结果表明混杂系统基于诊断键合图的模式跟踪方法具有有效性和可行性.
In this paper ,according to the law of conservation of energy ,the power expression of hybrid system was built for mode identification and tracking .Firstly ,the authors modelled the hybrid system with bond graph ,then made a construction of diagnosis hybrid bond graph for every suspected mode and derivated the power expression .Through the analysis of the residual of diagnosis hybrid bond graph generated ,the current mode of the hybrid system could be determined .Finally ,this method was simulated and analyzed by simulation in 20-sim bond graph simulation software .The experiment results indicated that the new method of mode tracking of hybrid system based on the diagnosis hybrid system bond graph possessed the feasibility and validity .
