Zhyvtsova L. Models and methods for improving the computer systems components of the parameters checkout of the objects’ spatial orientation

The dissertation is devoted to the development of models and methods for components improvement to reduce errors by angular parameters determining in computer systems of the objects’spatial orientation controlling by developing of the transducer mathematical models taking into account errors from destabilizing factors with preliminary mathematical processing of measurement information. A method for error compensation and a method for estimating the instrumental errors of three two-stage float transducers of the zenith and sight angles were developed. The method was developed for converting the angular parameters of transducers, which takes into account their distortions in the process of inclinometer rearranging in the drill pipe. Using the method of successive approximations, an additional error was obtained from the vibration of a two-component float transducer of the zenith and sight angles and a liquid transducer of the zenith angle. It is shown that a decrease in the additional error is achieved by lowering the natural oscillation frequency of the transducer in comparison with the frequency of vibrations and increasing its degree of damping. Experimental studies of the inclinometer, realized by a two-component accelerometer transducer and a liquid-to-air transducer of the zenith angle completely confirm the theoretical results and adequacy of the developed mathematical models.
