Background. The work is dedicated to the development of methods for dynamic measurements of multi-touch systems, which is an important problem in view of the fact that in the operation of multi-sensor systems, it is necessary to analyze and process large amounts of information of different nature. Multisensor systems are the object of research. The subject of the study is the identification methods, the purpose of which is to create a mathematical model of Multisensor systems. The paper provides an example of determining the pulse transition function of a liquidanalytical measuring system performed on fiber-optic liquid level detectors to determine the qualitative and quantitative content of impurities in the controlled liquid.
Methods. The methods proposed in this paper are based on identification methods. The determination of the pulse transition function is carried out by the results of a series of tests for discrete non–stationary systems, mathematical models of which are described by the input-output models.
Results. A mathematical model of the liquid-analytical measuring system for the qualitative and quantitative content of impurities of the test liquid is proposed.
Conclusions. The obtained results can be used in the development of mathematical models of Multisensor systems performed on various element bases.
