【摘要】 利用20-sim软件的功能,可以对非线性电路进行直接面向方程的仿真分析,也可以在现有非线性电路的基础上,转换成相应的键合图模型,利用键合图理论进行仿真分析。为了对这两种仿真分析方法进行对比分析,选取杜芬方程作为研究对象,提出了运算放大器的键合图模型,分别用图形化的方法与键合图方法进行了仿真,并对两种方法进行了结论性的比较。更多还原

【Abstract】 Depending on the software of 20-sim,the simulation and analysis about non-linear circuit is done in the form of equations,based on the theory of bond-graph.Using duffing equation as the object of research and an equivalent model based on the theory of bond-graph is proposed to compare the two methods.At last,there is a comparison between the methods.更多还原
