Dynamic Simulation Instrument for Numerical Solutions of Differential Equation Based on Labview

给出了基于LabVIEW的微分方程数值解虚拟动态仿真仪的设计方法。利用该仿真仪可以方便地研究当连续改变微分方程的系数或初始条件时其解的动态行为。这种动态行为分别由曲线和数字两种方式直观显示。仿真仪为微分方程的数值求解或控制系统的设计及动态特性的研究提供了图示仿真仪器。

The design method of virtual dynamic simulation instrument for numerical solutions of differential equation based on LabVIEW is proposed. The solution＇s dynamic behavior, while the coefficient and initial conditions of the differenti- al equation are changed continuously, is studied expediently in the simulation instrument. The dynamic behavior is displayed intuitionistic by both patterns of curve and numerals. The simulation instrument provide with diagrammatic emulation mode for numerical solutions of differential equation or design and research of dynamic characteristics in control system.
