Model Predictive Technology Based Integrated Orbit and Attitude Control of Inner-Formation Gravity Field Measurement Satellite

摘要：

The Inner-Formation gravity field measurement satellite (IFS) was proposed to measure Earths gravity field with high precision through precise orbit determination and relative state measurement. A coupled orbit and attitude linear model was constructed for the Inner-Formation during steadystate phase. The output was approximated by Taylor series expansion, and the facility capacities and system performances were transformed into adaptive constraints. The optimal control for integrated orbit and attitude control was obtained through the combination of model predictive control (MPC) technology and quadratic programming. Simulation results demonstrated that the MPC technology was a feasible and effective solution to the integrated orbit and attitude control for IFS.
