摘　　要：基于电学和动力学广泛的相似性,针对动力学实验可观测性差,从控制角度,用电子模拟计算机实现传递函数。以受力拓扑为基础,从最基本动力学元件弹簧、阻尼器和质量块的等效模块开始,组合成单自由度、空间多自由度系统等基本结构,说明拓扑一致和简单可加;最后结合电路发展现状和趋势,给出了对复杂系统的嵌入式设计混合仿真构架。由于传递函数相同,方法对实际动力学控制器设计也具有一定意义。Aimed at ugly observability in dynamic experiment, electronic analoge computer is employed to implement transfer function for electricity and dynamics general equality from control theory point.Based on load topology, by starting from parallel module of the most basical dynamic units of spring,damper and mass,combinating basical structure,i.e.,single motion freedom and multiple motion freedom in space,indicates uniformity and additivity; According to actual state and trendency,complex system hybird simulation framework is presented by In-System Programmability.For the same transfer function,this conception will play important role in real dynamic controller designing.
