DEVELOPMENT OF INDUCTIVE SENSOR BASED ON RANDOM OSCILLATOR

Abstract

The purpose of the work consists in the investigation of the possibility to use a random oscillator with the inductive coil as an inductive sensor. The work problems: methods development for the synthesis of a random oscillator with the inductive coil; development and investigation of methods for the analysis of oscillations in a random circuit at target bringing to a sensitive coil; an experimental confirmation of the results obtained theoretically. The investigation methods used in the work: a simulation, a computer experiment, a nature experiment. The investigation results: a confirmation of the hypothesis, lying in the basis of the investigation, on the applicability of random oscillators in sensor applications; a procedure for the synthesis of random oscillators with the inductive coil based on a specified random system of differential equations; data on the applicability of different kinds of the analysis of oscillations for the emphasis of information on the parameter measured, methods for these data processing. The novelty of this paper consists in that this is the first Russian language work on random sensors – a new promising direction of investigations in the field on non-linear dynamics. In this work for the first time there is used a random oscillator for the prototype formation of an approximation industrial sensor with a cup core. Conclusions: 1. On the basis of a random oscillator specified with a differential equation there may by synthesized a sensitive electric analogue circuit. 2. Using a simple geometrical analysis of an attractor it is possible to define a value of the parameter (inductivity) under measurement with high accuracy and to transform this value into data on a distance to an aim.
