A decoupling trajectory tracking method for gliding reentry vehicles is presented to improve the reliability of the guidance system. Function relations between state variables and control variables are analyzed. To reduce the coupling between control channels, the multiple-input multiple-output (MIMO) tracking system is separated into a series of two single-input single-output (SISO) subsystems. Tracking...
This paper mainly considers a lunar return skip entry trajectory tracking problem. The flight range and duration time of lunar return entry are rather long, so the effect of the rotation of the Earth should be considered. The guidance dynamics have more nonlinearities and couplings considering the rotation of the Earth, which make the trajectory tracking more difficult. In the existing literature,...
This paper presents a new solution to the motion control problem for a rotary wing vehicle powered by four rotors. The proposed control structure is a parallel scheme consisting of a partial state saturated feedback to control the vehicle altitude and a partial feedback linearizing feedback to control the planar vehicle's position. It is shown that the resulting closed-loop dynamics has a local asymptotic...
