考虑控制饱和的卫星姿态控制器设计

Abstract

Abstract: The problem addressed is the modified rodrigues parameter (MRP) based attitude control for rigid spacecraft subject to control input constraints.First a full state feedback controller is proposed, and the Lyapunov theory is employed to prove the global asymptotic stability of the zero equilibrium points of the closed loop system.Then an output feedback control scheme that is dependent on MRP is designed without angular velocity measurements.On the other hand, by introducing ahyperbolic tangent saturation function into the control scheme, it can be concluded that the control input saturation problem can be effectively restrained so long as the control parameters are selected to satisfy a specific inequality.Simulation results demonstrate the effectiveness and feasibility of the proposed control scheme.
