The Least Square Recurrence Method for Deriving the Simplified T/C Sectional Mathematic Model

提出一种基于递推最小二乘估计的求取热电偶分段简化数学模型的方法。该方法可用来解决带微机的温度仪表的非线性校正问题,文中还给出了程序框图。

A method for deriving the simplified T/C sectional mathematic model based on least square recurrence is presented. By using this method, the nonlinear correction problem of microcomputer-based tempera-ture measuring instruments can be solved. The flowchart of the problem is given.
