To address the trajectory tracking problem of missiles, an optimal disturbance rejection guidance law (ODRGL) in three dimensions is proposed under the premise of uncontrollable speed. Error models of the actual and the reference trajectory are built in channels of pitch and yaw, respectively.

Adaptive Robust Three-dimensional Trajectory Tracking for Actively Articulated Tracked Vehicles
Journal of Field Robotics, 2016A new approach is proposed for an adaptive robust three-dimensional (3D) trajectory-tracking controller design. The controller is modeled for actively articulated tracked vehicles (AATVs). These vehicles have active subtracks, called flippers, linked to the ends of the main tracks, to extend the locomotion capabilities in hazardous environments, such ...

Three-dimensional trajectory tracking control of an underactuated AUV
2017 29th Chinese Control And Decision Conference (CCDC), 2017To deal with the three-dimensional trajectory tracking control problem for an underactuated AUV, a non-smooth controller based on adding a power integrator approach is designed in this paper. Firstly, the trajectory tracking error system is established based on the kinematic equation and dynamic equation of underactuated AUV.

Motion planning and trajectory tracking for three-dimensional Poiseuille flow
Journal of Fluid Mechanics, 2009We present the first solution to a boundary motion planning problem for the Navier–Stokes equations, linearized around the parabolic equilibrium in a three-dimensional channel flow. The pressure and skin friction at one wall are chosen as the reference outputs as they are the most readily measurable ‘wall-restricted’ quantities in experimental fluid ...

This paper aims to tackle the three-dimensional trajectory tracking problems of small fixed-wing unmanned aerial vehicles subject to nonlinearities, uncertainties and wind disturbances via adaptive techniques. The control objective is to efficiently control the thrust and the deflections of control surfaces to ensure the unmanned aerial vehicle arrives

A new sliding mode tracking guidance based on three-dimensional trajectory
2018 Chinese Control And Decision Conference (CCDC), 2018With multiple path constraints taken into consideration during hypersonic glide phase, a new sliding mode tracking guidance based on three-dimensional trajectory is proposed. Firstly, on the basis of entry vehicle dynamics and geometrical transformation, the dynamics formulation of crossrange parameter is derived.
