The trajectory control problem, defined as making a vehicle follow a pre-established path in
space, can be solved by means of trajectory tracking or path following. In the trajectory …

A guidance concept to impose a desired impact time is presented and investigated. The
guidance concept is based on the geometrical principle that constrains the interceptor to …

TARGET tracking techniques allow aircraft to achieve surveillance objectives like convoy
protection, area surveillance, and distributed atmospheric volume sampling. Tracking is …

A three-dimensional nonlinear guidance law for path-following is proposed using differential
geometry of space curves. The proposed guidance law makes a vehicle converge to and …

For the automatic tracking of unknown moving targets on the ground, most of the commonly
used methods involve circling above the target. With such a tracking mode, there is a moving …

TODAY, autonomous unmanned aerial vehicles (UAVs) are increasingly more widely used.
Various control strategies have been developed to increase the level of autonomy. Typical …

In this paper, a new trajectory-following guidance scheme based on the combination of the
virtual target concept and a missile terminal guidance law is proposed. A line-of-sight (LOS) …

This paper addresses the problem of minimum-effort waypoint-following guidance
with/without arrival angle constraints of an unmanned aerial vehicle. By using a linearized …

AERIAL refueling is the process of transferring fuel from one aircraft (the tanker) to another
(the receiver) during flight. It has been used as a standard method to increase range and …

The control inputs of a fixed-wing unmanned aerial vehicle (UAV) are affected by external
environment, the largest mechanical limits and energy limits. It is essential to consider the …
