摘要
介绍了工业控制系统和测量系统非线性校正的基本原理和方法,重点论述了在控制系统和数据采集系统中非线性校正的实际应用。实践证明采用最小二乘法曲线拟合矫正能较好地解决非线性环节控制和测量系统中的精度问题。
The measurement system of industrial control systems and the basic principles and non-linear calibration methods are described,focused on the control system and data acquisition system in the practical application of non-linear correction,proven method of least squares curve fitting using correction can better solve the non-linear part of the control and measurement system in the precision of the problem.
