变结构系统的键合图仿真

Bond graph simulation of variable structure system

针对一类随开关量改变其系统结构的物理系统 ,提出用键合图对其各个状态进行分析和建模 ,在引入与各开关元件对应的逻辑变量的前提下 ,列写系统的统一的状态方程式。文中分别以机械系统、电系统和空气热力学系统的各一个实例进行了讨论 。

Aimed at a class of physical system with its systematic structure be changed according to switching amount, and by the use of bond graph to carry out analysis and modeling upon their various states was proposed. Under the premise of introducing the logical variables corresponding to every switching element, the unified state equation of the system was worked out. Discussions were conducted in this paper by taking one each living case separately in the mechanical system, the electric system and the aerothermodynamics system; and the relevant simulation results were presented.
