This paper describes the measurement system of industrial control systems and the basic principles and non-linear calibration methods, focuses 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.
