CONTROL SYSTEM OF BRAZILIAN LAUNCHER

摘要

This work describes the whole functional structure of the control systems used in the Brazilian Satellite Launcher VLS.. It is focused the computational aspects and the implementation of the algorithms of the several loops that compose the control complex. To accomplish its mission, the control complex must have suitable algorithms and control loops, that should act during the powered and ballistics phases. This conception is related with the physical accomplishment of the vehicle that defines the actuators and the convenient sequence which they ones are used. The loops and algorithms have for objective to force the vehicle, at least, to come close to the reference path (or nominal), minimizing disturbances effects. The navigation, guidance-loop compensation and control systems of VLS are reviewed with the respect to the system engineering. Operational requirements and design aspects determine the synthesis and the implementation of the system.
