The purpose of the work is to research methods of reducing dynamic measurement errors in multiparameter measurement information systems. Research methods – system analysis, mathematical modeling and experimental research, theory of probability and random processes, mathematical statistics and theory of measurement errors. In chapter 1, the method of using the Koopman operator for linearization of nonlinear measuring information systems is considered. It is shown that the use of the Koopman operator makes it possible to use linear transformations in the analysis of nonlinear inertial measurement systems. The global linearization of the dynamical system model is a great advantage of the Koopman operator, although the infinite dimension of the operator must be taken into account. The method of increasing the completeness of information in the information technologies of autonomous mobile robots has been improved. Modern information technologies used on trams and in the construction of tunnels are considered Chapter 2 summarizes information on methods of reducing dynamic measurement errors of on-board measurement information systems in the machine-building and road construction industries. The method and results of experimental studies of the effect of non-identity of dynamic load sensors on measurement errors are considered. The results of experimental research on the mutual connection of strain gauges during static and dynamic measurements of plane loads on structural elements of a road vehicle are analyzed. The results of the study of methods for reducing dynamic errors of measuring air flow parameters in measuring information systems are analyzed. The method of assessing the uncertainty of air flow velocity measurements with a two-channel meter is considered, and the data of experimental studies are given.
