摘要
研究利用键合图模型在Matlab Simulink环境下进行模拟电路仿真,将模拟电路的键合图模型转化为Matlab Simulink中的功能模块后进行仿真,针对仿真过程中由于开关状态切换或电路短路、断路故障造成的键合图能量路径改变的问题,使用键合图因果关系重分配算法在线改变模块内部因果关系,实现模拟电路的实时仿真。
The simulation of analog circuit was studied in Matlab Simulink environment using the bond graph model,in advance of the simulation the bond graph elements of analog circuit were transformed to the function blocks in Matlab Simulink enviroment.To resolve the problem of the changes of energy path caused by switching off,shortcut and breakout in the circuit,the causality reassignment algorithm was adopted to change the block internal causality,and realized real time simulation of the analog circuit.
