| Abstract | A methodology for design of an intelligent helicopter flight controller is presented in this paper. The methodology combines artificial neural network, genetic algorithms, conventional PID-controllers, and fuzzy logic algorithms in the design procedure. In this approach, the design of an intelligent controller is based on experimental data collected from actual helicopter flight and not based on analytical models. A neural network is trained to learn the dynamic characteristics of the helicopter. Based on the neural model, the coefficients of a PID-controller used for blade angle control are searched for using genetic algorithms. The main rotor speed controller is designed using fuzzy logic algorithm based on knowledge generated from understanding the aerodynamic theory and analyzing the helicopter experimental flight data. The intelligent helicopter flight controller is formed by combining the blade angle PID-controller and the rotor speed fuzzy controller. Simulation results showed that for desired altitude input H/sub d/, the intelligent controller was able to generate proper control signals for both the blade angle control and the rotor speed control. The helicopter model altitude output H/sub t/ follows the desired altitude input H/sub d/. The design procedures, theoretical background, results and conclusions are presented in this paper. |

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.
