Application of a model-based nonlinear attitude control for quadrotor UAVs
… this thesis proposes a computationally-e cient position estimator for the quadrotor's operation. The position estimator detects visual markers of an image from the camera, and computes the quadrotor's position. The position estimator was also evaluated by experiments.

Position Sensorless Implementation for a Linear Switched Reluctance Machine
The development of an add-on sensorless position estimator for a 4.8 m Linear Switched Reluctance Machine (LSRM) with minimal modifications to the transducer-based controller is investigated for the first time in this study. LSRMs require position feedback for closed-loop control but present a low …

Unified Control for the Permanent Magnet Generator and Rectifier System
… loop, reactive control loop and speed and rotor position estimator loop. Thirdly, the hardware is developed and the experiment is conducted to verify the control strategy. Fourthly, a method to optimize the overall system efficiency by appropriate reactive power distribution is proposed. The two …

Embedded object detection and position estimation for RoboCup Small Size League
… the robot has to detect and estimate the position of other objects on the field so it can score goals and move without colliding with other robots. Object detection models often use monocular images as the input, but calculating the relative position of an object given a monocular image is …
