Abstract | In this paper will be presented a novel approach to design and optimization of attitude and path tracking controller for quad-rotor robots based on Learning Automata algorithm. The proposed method has superior features, including easy implementation, stable and fast convergence characteristic, and good computational efficiency while compared with others learning approaches. The quad-rotor robots have become increasingly important in recent years as platforms for both research and commercial applications. For this reason, we propose a set-up that can be used to the training and evaluation of the quad-rotor controllers in realistic conditions. First, the vehicle dynamics and mathematical model are presented. The attitude and path tracking control strategies for the robot are formulated. Next, the method used to adjust the parameters of the controllers through the Reinforcement Learning algorithm is discussed. The simulation environment is composed by 2 host computers where one host executes the control loops and the training algorithm implemented in Matlab/Simulink. The other host runs the quad-rotor model using the X-Plane Flight Simulator. The two hosts communicate using UDP (User Data Protocol) over a standard Ethernet wired network. Using this framework is possible tuning the parameters of the controllers for a nonlinear aircraft which interacts with the environment, taken into account, the aerodynamics effects present during the quad-rotor flight. This simulation environment showed to be a good set-up for researchers to investigate the application of learning algorithms to adjust the control laws for several flight maneuvers and conditions. Finally, the results obtained from the controllers adjusted by the Learning Automata algorithm are presented. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
