Research ArticleOpen accessEvery word in the titleQuadrotor Obstacle Avoidance Based on Integral BacksteppingLianchuan Zhang, Young Baik Kim, Kil To ChongThis paper addressed obstacle avoidance problem of a quadrotor in outdoor environment. Path planning was finished by employing classical Dijkstra algorithm and the controller of the quadrotor adopted integral backstepping method. In order to get a smooth trajectory with time optimal and acceleration constraints properties, quantic polynomials were utilized to generate trajectory file. The scheme is particularly practical and useful … …American Journal of Applied Sciences, Vol. 13, Issue 7 · 27 Jul 2016 · 6,981 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFeedback Control of Quad-Rotors with a Matlab-Based SimulatorStephen Armah, Sun Yi, Wonchang Choi, Dongchul ShinPrecise regulation of position and attitude (roll, pitch and yaw) is one of the most critical tasks to be considered in designing controllers for quadrotor types of Unmanned Aerial Vehicles (UAVs). The MATLAB-based simulator for quadrotors using PD-feedback control to achieve stabilization was developed. MATLAB/Simulink models are used to design and validate the control algorithms and the simulation results are … …American Journal of Applied Sciences, Vol. 13, Issue 6 · 23 Jun 2016 · 7,865 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdaptive and Neural Network Based Control of Pitch of Unmanned Aerial VehiclesMackenzie T. Matthews, Sun YiThe objective is to develop a new control strategy for quadrotor types of Unmanned Aerial Systems (UAVs) that assist in closing the existing research gaps between the undesired uncertainties and current control systems. This research investigates a system modeling and the effectiveness of error elimination through adaptation in the change of the plant/system’s output. The UAV is controlled via Wi-Fi … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 18 Nov 2019 · 6,489 accessesView PDFCite
