COEFFICIENTS OF ERRORS OF STABILIZATION OF LAUNCH VEHICLE ROTATION MOTION

Avdeev V. V.

      The research goal is to determine dependencies of errors factors for compensating a constant and ramp exci-tation on coefficients of motion equations, parameters of actuating and correcting devices considering a given stability margin. Dependencies are derived by analytic methods using known concepts of the automatic control theory. Vectors of error coefficients have been first linked to parameters of the stabilization system of a plane rotation of a ”solid” rocket in the form of analytic expressions. New relations for building a bond of the stability region on planes of two coefficients of the control action.

      The paper results can be used for developing the stabilization system due to linking between its parameters and compensation errors and provide an initial approximation for calculations on more accurate models using numerical methods.
