ALGORITHM OF PRESSURE MEASUREMENTS CORRECTION FOR LINEAR PART OF TRUNK PIPELINE
(pp. 43-48)

Abstract. The article deals with a problem of pressure measurements adjustment. The work relevance is due to the need for improving the measurements processing methods. The problem is solved for linear parts of trunk pipeline. Approved processing apparatus of stochastic dependencies is used and a comparative analysis of the different measurement error handling models is conducted. A hybrid model which contains parametric and nonparametric components is used. A parametric part is a priori knowledge about the process of distribution of pressure along the pipeline profile. Nonparametric part is the actual information and it is presented by measurement samples. The problem of measurements forecast is solved by using the proposed approach. The obtained results allow us to solve an identification problem of system components states and pipeline in general. Using the proposed approach improves the accuracy of modeling of the main pipeline pressure distribution process, and therefore, improves the quality of technological systems of the pipeline control.

Keywords: adaptive algorithm, hybrid model, error correction, pressure sensor.
