| Abstract | The main research aim of this thesis is to design the system architecture of the Stewart Platform in order to make the related operational processes being more efficient and convenient. As the result, we developed a graphical user interface for the goal of effective adjustment of corresponding control parameters, which is implemented by I/O signal cards to transmit the data files between the control console and the platform. In other words, within the limited working space, we can control the motion cueing of the platform arbitrarily and immediately. The Functional Neural Fuzzy Controller (FNFC) was developed by our Lab, while the corresponding algorithms consist of the structure and parameter learning processes. The process of structure learning is based on the entropy measurement to decide whether there should be added one more fuzzy rule, and the backpropagation method is used in the parameter learning to adjust all free parameters of the neural network. Comparing to the existing PID controllers for evaluation of motion platforms, our approach could provide better performance, reduce the corresponding complexity, and minimize the error between actual length and commanded length of the platform's actuators. In order to maximize the working space within the realistic limited range and to simulate the large scale motions of the relative acceleration and angular velocity and to make experienced pilots feeling more realistically under their operations, we applied the algorithm of the washout filter to immediately and smoothly perform each commanded motion cues on our platform. Lastly, we compared our proposed approach with other methods to prove the effectiveness of our neural architecture and the corresponding algorithms. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
