Problems of designing autopilot system for rocket vehicle arise from fact that rocket structures are highly flexible; mathematical model is derived which is complete enough for accurate determination of dynamics of vehicle, and yet of low enough order to allow computer simulation; included in model are aerodynamic forces, inertia reaction torques on vehicle motion due to nozzle dynamics; flexible vehicle (bending), liquid fuel (sloshing), crosscouplings of bending and sloshing modes with rigid body modes because of engine thrust, couplings of bending and sloshing modes with engine dynamics, and sensor dynamics; results of computer simulation of flights for linear and bang-bang control.
