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.

Modeling and optimal three-dimensional trajectory tracking for an autonomous underwater vehicle
2016 IEEE International Conference on Advanced Intelligent Mechatronics (AIM), 2016This paper introduces a new approach for designing a simplified control law, which controls an autonomous underwater vehicle (AUV) to track a given 3D trajectory. To get a Linear Time Variant (LTV) state space model, the 6 degrees of freedom (6DOF) dynamics and kinematics model of the AUV is linearized about the given desired 3D trajectory it needs to ...

Globally finite-time stable three-dimensional trajectory-tracking control of underactuated UUVs
Ocean Engineering, 2019Abstract In this paper, the subject of the spatial trajectory-tracking control for underactuated unmanned underwater vehicles (UUVs) is addressed in the presence of model parameter perturbation and unknown ocean currents. The spatial trajectory-tracking guidance is established based on the dynamic virtual vehicle method, which continuously computes ...

Journal of Shanghai Jiaotong University (Science), 2020
This paper addresses a three-dimensional (3D) trajectory tracking problem of underactuated autonomous underwater vehicles (AUVs) subjected to input saturation and external disturbances. The proposed controller can achieve practical convergence of tracking errors for general reference trajectories, including persistently exciting (PE) time varying ...

Three Dimensional Trajectory Tracking for Unmanned Aerial Vehicles in Time-Varying Winds
2015 Fifth International Conference on Instrumentation and Measurement, Computer, Communication and Control (IMCCC), 2015In this paper, a control law for three dimensional trajectory tracking for unmanned aerial vehicles is developed. The control law is based on back stepping method. The parameters of the control law are tuned by genetic algorithm. Simulations show that the effectiveness of the control law and the parameter tuning method.

Volleyball Movement Trajectory Analysis Based on Three-Dimensional Visual Tracking
Applied Mechanics and Materials, 2014in volleyball movement process, there is greater uncertainty in velocity and position of movement. Using traditional algorithms for volleyball movement trajectory analysis, it cannot get changes situation of volleyball movement trajectory, resulting in that there is a big deviation in volleyball movement trajectory analysis, and the accuracy of ...

Obtaining three-dimensional trajectory of multiple fish in water tank via video tracking
Multimedia Tools and Applications, 2018Accurately and reliably obtaining the three-dimensional motion data of individuals in fish schools is not only valuable for fish behaviour analysis and hydrodynamics studies but also be helpful in areas such as bio-inspired robot design. Video tracking is the most effective gateway to obtain the quantitative motion data of continuously moving objects ...
