Multi-Objective Optimization Applied to Real-Time Command Problem of Spacecraft Thrusters

摘要: A novel approach to solve the real-time command problem of spacecraft thrusters, called thruster multi-objective method, is proposed in this paper. The reaction control system technology uses a set thrusters special setup simultaneously provide force and torque spacecraft. management function calculates all candidate solutions that coupling problem. Then, discrete optimization method selects at every cycle best combination their firing time duration, which optimizes group four objectives: error, propellant mass consumption, total number pulses. included coupled translational attitude applied final rendezvous scenario. Furthermore, elements guidance, navigation, loop are accurately designed implemented simulation framework. Results indicate...
