VELOCITY'S MEASUREMENT OF METHODICAL ERROR RESEARCH AT MOVEMENT OF PLASMA IN ELECTRODYNAMICS LAUNCHER BY METHOD OF COORDINATE FUNCTION WITH LIQUIDATION OF «DEAD ZONES»
(pp. 44-50)

Abstract. Study methodical error of measurement of the instantaneous velocity of the moving plasmid various modifications KF method with the elimination of “dead zones” have been carried out using an analytical model of induction position sensor. The error was calculated using the guaranteed approach (method worst case). Methodical error KF switching method, the summation of the CF, and combinations of these methods eliminate the “dead zones” KF, was designed in the area from 1.75 to 2 m (i.e. at the end of the rail link). A comparative analysis of the methodical error of measurement of the instantaneous velocity of plasma motion in the magneto-plasma accelerator using the method of coordinate function (CF) with a variety of ways to eliminate its “dead zones” The values of a methodical error for three modifications of the method of CF:. KF method with CF switching method KF-add CF and combined method KF switching and summing KF. On the computer performed comparative calculations EMF and magnetic induction at the output of the induction position sensor. Also, made the CF calculations for all modifications KF method. The calculations of the rail channel length was chosen to be 2.0 m. In order to find the moment of switching a CF the other was found each of these derivative functions as a switching moments KF position to the other following coordinates were chosen 0.5 m, 0.75 m, 1.25 m, 1.75 m.

Keywords: electrodynamics launcher, instantaneous velocity measuring, method of coordinate function.
