According to the idea of reference-trajectory guidance, the angle of attack and bank angle commands are designed using sliding mode control (SMC) method to make the reference-trajectory tacking error converge into a small neighborhood of zero.
Based on the idea of reference-trajectory guidance, an integrated guidance and control (IGC) design approach is proposed for the landing of a reusable launch vehicle (RLV) by using backstepping and adaptive control.
A class of trajectory shaping guidance laws is extended, unified, and generalized.
In this paper, the drag-based trajectory tracking guidance problem is investigated for Mars entry vehicle subject to uncertainties.
Firstly, the horizontal trajectory tracking guidance laws are established by the virtual vehicle method, where the tracking error equations are derived.
In this paper, a new adaptive trajectory shaping guidance scheme based on the adaptive fuzzy inference system, which is capable of generating a variety of trajectories for efficient target interception, is presented.
However, robot based on this training strategy only moves the patient along predefined, fixed trajectories, and the guidance provided by the robot is so strong that it suppresses the voluntary motor control of the patient [12].
The corresponding reachable and controllable set analysis, trajectory optimization, and advanced guidance methods are also revealed.
A smooth HOSM guidance generates flight path trajectory angular rates and attitude rate commands.
With this assumption the trajectory problem (also called the guidance problem) and the attitude problem (also called the control problem) can be addressed separately.
In this paper, a sliding mode control algorithm combined with a fuzzy control scheme is developed for the trajectory control of a command guidance system.
