摘要
为了评价控制系统的动态性能,以二阶线性系统传递函数为基础,在虚拟仪器软件平台LabVIEW上构建了二阶动态特性测试系统。利用仿真的方法,研究了在给定单位阶跃输入信号下如何求取系统的输出信号,得出了二阶线性系统的单位阶跃响应随阻尼比不同而变化的情况,最后通过实例给出了部分仿真结果。实验表明,仿真结果与理论分析结果一致。
In order to estimate the dynamic characteristics of control systems, on the basis of transfer function, the dynamic behavior test system of two orders is constructed based on the Virtual Instrument software platform LabVIEW. Through detailed simulation analysis, this paper studies how to obtain systematic output signals from given unit step input signals, and find that the unit step response of two order liner system varies with the changes of damping ratio. Finally, through the examples, the part simulation results are given. The results show that the simulation is consistent with the theoretic analysis.
