Paper Abstract

This article discusses the principle and performance of a controlled sensitive element. A concept of the cryogenicoptical sensor based on competitive the adaptive sensitive element applicable to a gravity meter sensor is considered. The sensor element is based on a magnetic levitation phenomenon, high-precision optical registration of levitating body mechanical coordinates, and robust signal processing tools. A controlled self-bearing probe dynamics is also analyzed. An dynamical approach to highly sensitive measurement of weak signal is presented. The robust signal estimation problem is considered, when signal are estimated via application of neural networks and when nonlinear measurements are used. The construction of the sensor is described. Simulation results support the mathematical, and the system characteristics are thus optimized.
