ABSTRACT

The problem of selection of the values of variable parameters of the digital stabilizer of the space stage of a booster rocket with a liquid jet engine on the active part of a flight trajectory, which provides the minimum value of the additive integral quadratic functional with unknown in advance weight coefficients, calculated based on solutions of the mathematical model of the perturbed motion of a closed stabilization system, and contains ordinary differential equations, and finite difference equations, with subsequent using software products Optimization Toolbox in the MATLAB interactive environment or Minimize in the MathCAD interactive environment and determination of unknown weighting coefficients of the additive functional. This approach enables the refusal of using the method of "frozen coefficients" and leads to a decrease in static error and an increase in the speed of the closed stabilization system. Using the example of the C5M space stage of the "Cyclone-3" launch vehicle, it was shown that solving the problem of parametric synthesis of a digital stabilizer using the stated method enables the 25 % increase in the system operation speed, get the several time increase in the stage stabilization accuracy and significantly weaken the effect of fluid oscillations in fuel and oxidizer tanks for stabilized stage motion. To reduce the static error of the closed stabilization system and providing it with the invariance property relative to the action of external perturbations, the values of the variable parameters of the stabilizer should be chosen variable during the motion along the active section of the flight trajectory of the launch vehicle.
