摘　　要：从一阶检测系统的阶跃响应出发 ,利用计算机实时采样的数据和推导的相关公式 ,可以精确的计算出检测系统的时间常数 ,同时 ,利用响应过程特性曲线 ,可以方便地“预测”出激励信号的大小 ,减小了系统的动态误差 ,缩短了检测时间 。Proceeding from the step response of single capacity detecting system,we can accurately calculate the time constant of detecting system with the help of the real time sampled data of computer and the associative formula of derivation,and we can easily 'predict' the size of the drive signal by means of the response curve.This method helps reduce the dynamic error of the system and shorten the detecting time,which is of great pratical value.

关 键 词：一阶检则系统 阶跃响应 动态误差 实时时间常数 预测算法 控制系统
