本文提出单输入单输出系统综合误差的两种计算方法,一种是由各档的系统误差和偶然误差合成综合误差的计算方法,另一种是由各档的分项误差(不重复误差、迟滞误差、不符合误差或线性误差)合成综合误差的计算方法。这两种方法同时都适用于线性和非线性系统,同时证明了这两种方法都相曲线拟合精度的计算方法是一致的。这样就使得单输入单输出系统综合误差的计算方法具有可靠的理论依据。在附录中线性和非线性系统各举一个实例。
In this paper, two methods of calculating the total error of single-input and single-output system are proposed. One is the method of calculating the synthesis error by system error and accidental error of each file, Hysteresis error, non-compliant error or linear error) Synthetic synthesis error calculation method. Both of these methods are suitable for both linear and nonlinear systems, and the method of calculating the curve fitting accuracy of these two methods is proved to be consistent. In this way, the calculation method of the integrated error of the single input and single output system has a reliable theoretical basis. An example is given in the appendix for linear and non-linear systems.
