摘要

研究表明,在工业条件下,当影响参数偏离归一化值时,很少对当前测量结果进行修正。现有的确定附加测量误差的方法是为了获得测量结果的真实值,对其进行修正计算,从而得出控制手段指标的当值。修正值由影响参数偏差的程度除以附加误差的归一化值确定。这种确定修正量的方法不够精确,因为它没有考虑附加测量误差对影响参数变化的非线性依赖,以及对控制手段输出信号的电流值的非线性依赖。为了确定测量参数的实值和附加误差,提出了积分型泛函方法。该方法的实质是在受测量范围限制的情况下,确定不同平面下标称和电流部件的静态特性。结果表明,平面差取决于控制手段输出信号的电流值和实值,以及影响参数的偏差。该方法允许仅通过控制手段的输出信号和影响参数的电流值计算被测参数的实际值。建立了测量参数的实值、控制手段输出信号的电流值与影响参数偏差之间的依赖关系。

Mathematical Models of Additional Measurement Errors of Control Means
Studies have shown that under industrial conditions there is rarely a correction of the current measurement result when the influencing parameter deviates from the normalized value. The existing method of determining the additional measurement error is that in order to obtain the real value of the measurement result, the correction is calculated, which leads to the current value of indexes of control means. The correction value is determined by dividing the degree of the influencing parameter deviation by the normalized value of the additional error. This method of determining the correction is not accurate enough, since it does not take into account the nonlinear dependence of the additional measurement error on the change in the influencing parameter, as well as on the current value of the output signal of control means. To determine the real value of the measured parameter and the additional error, the method of integral-type functional is proposed. The essence of the method is in determining the difference of planes under the nominal and current parts of the static characteristic, limited by the measurement range. It is shown that the planes difference depends on the current and real values of the output signal of control means, as well as on the influencing parameter deviation. The method allows calculating the real values of the measured parameter only by the output signal of control means and the current values of the influencing parameter. The dependencies between the real value of the measured parameter, the current value of the output signal of control means and the influencing parameter deviation are established.
