Non-holonomic model-based predictive output tracking of an unknown three-dimensional trajectory
Proceedings of the 37th IEEE Conference on Decision and Control (Cat. No.98CH36171), 2002We present a control strategy to track a target trajectory in space with a non-holonomic vehicle. Only noisy, point-wise measurements of the target are available at each time, so that no global optimality can be achieved. Instead, we propose a causal, predictive output-feedback control strategy based upon the recursive approximation of the target with ...

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.

Mixed fuzzy sliding mode three-dimensional trajectory tracking control for a wheeled mobile robot
2017 32nd Youth Academic Annual Conference of Chinese Association of Automation (YAC), 2017A three-dimensional (3d) trajectory tracking controller for a wheeled mobile robot via adaptive fuzzy sliding mode (AFSM) technique is designed in this paper. To begin, according to the coordinate transformation theory, the wheeled mobile robot dynamics equation and position equation are obtained.

In solution magnetic resonance (MR), manipulating the spin system in real time is difficult to implement in part due to the challenge of measuring the longitudinal magnetization within the constraints of MR detection hardware. Here we exploit the dynamical frequency shift induced by the radiation damping feedback field to estimate the longitudinal ...

Nowadays, due to advantages of maneuverability, portability and low cost, the mini quadrotor unmanned aerial vehicle (UAV) catches much attention. In some special applications such as narrow space search, stealth detection and cooperative detection in huge region, the mini quadrotor UAV is more suitable than a big one.

In this paper, bio-inspired models are introduced, combining with the backstepping control. A three-dimensional dynamic velocity trajectory tracking controller is designed. In order to solve the problem of “differential explosion” in the backstepping control of the underactuated unmanned underwater vehicle (UUV) three-dimensional trajectory tracking ...

This article proposed a novel control approach for trajectory tracking of robotic airships. First, the nonlinear dynamics model of a robotic airship is derived and formulated. Second, a sliding mode controller is designed to track the commanded trajectory for its robustness against parametric variations and external disturbances.
