An improved MT-NT algorithm for fault detection and correction is introduced. The improved algorithm adopts successive detection and correction strategies to effectively solve the problem of rank reduction of coefficient matrices in the process of detecting fault errors, reducing the amount of computation and increasing the usability and completeness of information. The block diagram and the steps of the algorithm are given, and the process measurement data correction software is compiled by object-oriented method and C + + language. After the example verification, this algorithm can effectively detect the fault error in the measurement data and avoid the rank-reduction of the coefficient matrix that appears in the calculation process, which is of certain practicality.
