A Switched Based Control Strategy for Target Tracking of Autonomous Robotic Vehicles using Range-only Measurements

Signal strength based scheme for following mobile IoT devices in dynamic environments

“…This could involve the avoidance of obstacles or path making. Control laws for tracking a target can be formulated with estimations of distance from the target [8], [9], [10], [11], [12], [13]. In [8], a tracking strategy is presented, where the distance from the target is estimated over time, by using the strength of a received signal.…”

“…According to [9], by using this strategy it is possible for the tracker to locate a moving target in a bounded time, given that the target's speed is up to half the speed of the tracker. A similar approach is followed in [10], but there the problem is solved using orientation and distance information from the target, while in [12] and [13], the problem is solved without knowledge of the orientation of the target, but only the estimated distance from it and its derivative.…”

Tracking of Ground Mobile Targets by Quadrotor Unmanned Aerial Vehicles

“…An optimal switching point based on velocity ratio between the UAV and the target is used as a switching criterion between these trajectories. Also authors in [39] have discussed a switching based control strategy for UAV target tracking problem using range-only measurement. A continuous cycle of two distinct phases have been introduced in this paper, one is following the bearing and another is repeating the previous step when the range is decreasing.…”
