Quad Rotorcraft Control: VisionBased Hovering and Navigation (Advances in Industrial Control),Used
Delivery time: 8-12 business days (International)
Quad Rotorcraft Control develops original control methods for the navigation and hovering flight of an autonomous miniquadrotor robotic helicopter. These methods use an imaging system and a combination of inertial and altitude sensors to localize and guide the movement of the unmanned aerial vehicle relative to its immediate environment.The history, classification and applications of UAVs are introduced, followed by a description of modelling techniques for quadrotors and the experimental platform itself. A control strategy for the improvement of attitude stabilization in quadrotors is then proposed and tested in realtime experiments. The strategy, based on the use lowcost components and with experimentallyestablished robustness, avoids drift in the UAVs angular position by the addition of an internal control loop to each electronic speed controller ensuring that, during hovering flight, all four motors turn at almost the same speed. The quadrotors Euler angles being very close to the origin, other sensors like GPS or imagesensing equipment can be incorporated to perform autonomous positioning or trajectorytracking tasks.Two visionbased strategies, each designed to deal with a specific kind of mission, are introduced and separately tested. The first stabilizes the quadrotor over a landing pad on the ground; it extracts the 3dimensional position using homography estimation and derives translational velocity by optical flow calculation. The second combines colourextraction and linedetection algorithms to control the quadrotors 3dimensional position and achieves forward velocity regulation during a roadfollowing task.In order to estimate the translationaldynamical characteristics of the quadrotor (relative position and translational velocity) as they evolve within a building or other unstructured, GPSdeprived environment, imaging, inertial and altitude sensors are combined in a state observer.The textgive the reader a current view of the problems encountered in UAV control, specifically those relating to quadrotor flying machines and it will interest researchers and graduate students working in that field. The visionbased control strategies presented help the reader to a better understanding of how an imaging system can be used to obtain the information required for performance of the hovering and navigation tasks ubiquitous in rotored UAV operation.
