| Summary: | Background. The principle of automated control and monitoring systems’ operation
is based on the widespread use of devices for measuring angular and linear displacement
At the same time, the main requirement for these devices is high reliability, safety and
properties of the output signal, convenient for further use. As a rule, the output signal of
devices for measuring the parameters of linear and angular displacements should be in digital
form at the present level of development. At the same time, the urgent task is to ensure
high accuracy of movements in the measuring transducers and the conversion of the initial
value into an electrical signal. Electrical form of the output signal of the primary measuring
transducer is most convenient for further processing and use in subsequent stages of robotic
systems and complexes. The purpose of the work is to develop measuring transducers based
on electromagnetic phase shifters of angular displacements based on a non-uniform magnetic
circuit with distributed parameters. Materials and methods. Research of the processes
occurring during the operation of an electromagnetic converter with a non-uniform magnetic
circuit with distributed parameters, which implements the functions of a linear phase
shifter. Results. A methodology and mathematical model have been developed. The technique
allows you to calculate the absolute error from the influence of any factor. The resulting
variance from the action of all factors will depend not only on the variance of each factor,
but will be the result of the interaction of these factors. With the help of a mathematical
model, studies of the developed measuring system were carried out in order to obtain a decomposition
of the absolute errors of the system into components along the axes of a multidimensional
space. Conclusions. The obtained research results consist in the use of the
methodology for the design of measuring systems of linear displacements to obtain tolerances
for the manufacture of individual elements of the electromagnetic system and the
formation of requirements for the characteristics of the measuring system blocks based on
the obtained mathematical model.
