摘要
介绍了一种基于LabVIEW的多功能控制系统虚拟设计与仿真仪。仿真仪可以方便地研究当控制系统的一个或多个参数变化时,系统时域和频域动态特性的变化状况。获得随系统参数变化而"动画式"连续变化的频域和时域曲线,并由相应坐标系对多项指标进行数字测量。使用改进的比例-积分-微分(PID)控制方法对系统实施校正。PID的各个参数可以通过仿真结果直接实时调整和选取,避免了繁复的计算和实验选择的交互影响,给出了PID调节器仿真设计的实用新方法。
A virtual multifunctional design and simulation instrument for control systems based on Lab VIEW was introduced. When changing one or several parameter in the control system the change situation of dynamic behavior in frequency and time domains of the systems was studied expediently in the simulation instrument. The consecutive transformation curve of ＂animation pattern＇ in the frequency and time domains with change of parameter in the system was obtained. The numeric measure for several performance indexes was achieved by the corresponding coordinate system. A control method with improvement proportionrnent- integral- differential （PID） was used to actualize emendation for the system. The several parameters of the PID were adjusted and selected directly on real time by means of the simulation result which avoided heavy and complicated computation and interaction of experiments. A new practicality method with simulation design for PID adjustor was provided
