Paper Abstract

The work concerns to the computerized techniques of quality estimation of automated top precision angle-code converters. Study of instrumental errors of a rotor position sensor (RPS) with use of goniometric rotary bench (GRB) was made, the plane angle accuracy being got from an optical interferential flat-mirror-zero-point module of original design and a photoelectric angle encoder of RON-905 type manufactured by the <<Heidenhein>> Corporation (Germany). Also a research was made of inaccuracies of the goniometric rotary bench itself, and also the methods have been developed for definition of inaccuracies due to dynamical behavior of measurement of an angle, and both for their algorithmic elimination. Study of systematic, random, and dynamical inaccuracies of both the standard sensor RON-905, and the tested one, RPS, was carried out. Research of dynamic inaccuracy of said angle measurements was made by means of interrelation between angular rate of rotation and changing of the measured angle interval from the interferential zero-label to the certain selected RON label. The latter data gave rise to close algorithmic elimination of a dynamical error arisen from RON own delay time. In this way, it became possible to calibrate the tested sensor in a very broad range of rotation rate and in several modes of rotation with a steady accuracy. The developed techniques provide calibration of sensors in a case of a rotary bench movement with the composite postulated law of a turn angle against time.
