摘要
对测量系统进行动态特性和精度理论研究必须建立测量系统的数学模型。针对传统建模方法的缺陷,研究分析了全系统动态误差建模理论与方法,该建模理论与方法充分考虑了系统内部各组成环节的信息,建立的模型能够反映实际测量系统内部各结构单元的传递特性随时间变化对系统测量精度的影响。该建模理论与方法具有普遍的适用意义,不管是动态测量系统还是静态测量系统,用该建模理论与方法都能够建立其全误差模型。最后利用全系统动态误差建模理论与方法建立了测微系统(百分表)的全误差模型,并进行了实验验证。
Invistigation of dynamic characteristics and accuracy theory about measuring system must build its mathematic model. Aimming at the limitations of traditional modeling methods, studying the whole--system dynamic error modeling theory was established, which considered sufficiently the information of build--in units of the measurement system, so the built model can reflect the timevarying change of the transfer behavior of the system. The modeling theory can be applied widespread. The whole-error modeling of the hundredth meter was built using this theory, then experimental results validate its correctness.
