| Abstract | The characteristic modeling problem of flight vehicles’ attitude dynamics is considered in this paper. In terms of the affine nonlinear system with triangle form of flight vehicles’ attitude dynamics, a general method is presented to compress the dynamics into the characteristic model parameters, by introducing the time scale of nonlinear systems and a class of system states related compress functions. The parameter region and limit of the characteristic model are also given. From the given parameter region it is seen that the bound of the characteristic model parameters is dependent on the sampling period, the modeling error, the system order and the system change rate. The modeling error of the established characteristic model can be arbitrarily small according to the control precision, showing the difference between the characteristic model and other model reduction methods, that is, no system information is lost using this approach. On the basis of this modeling approach, the characteristic model of the flexible satellite attitude is established, as well as the bound and limit of the parameters, which sets a theoretical foundation for characteristic model based control design of flight vehicles. |

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.
