摘要 针对自动控制系统中具有时滞高阶被控制对象,介绍了一种基于二维搜索法处理对象阶跃响应曲线的新方法。将自动控制系统中的对象在阶跃响应曲线上得到的数据输入计算机,采用内外层循环的二维搜索法,计算对象特性的参数T(时间常数)和τ(滞后时间),提出了化简精度的判定指标—方差和最小。在处理时滞高阶被控制对象阶跃响应曲线过程中,该方法排除了人们使用图解法时的主观随机性,具有简单易行、高精度量化的特点。实践证明,该方法可以方便地处理各种时滞高阶被控对象阶跃响应曲线。 For the controlled object with time delay and high-order in automatic control system,a new method is introduced to confirm the object feature.The method handles the curve of the step response of the object based on planar search method.The data obtained in the step response are put into computer.Through planar search method inside and outside,the feature parameters of the object,T(time constant)and τ(hysteresis time)are confrmed.Then a minimum sum of variance as the determinant guideline is put forward to s...
