| Abstract | This paper aims to guarantee high-precision tracking of the desired optical path difference velocity for a Fourier transform spectrometer (FTS) in a space exploration system with time-varying parameters and nonlinear dynamics. A novel characteristic model-based adaptive discrete-time sliding mode control (ADSMC) scheme is proposed. The design of the ADSMC includes characteristic modeling, characteristic model-based discrete-time sliding mode control, and the estimator of the uncertain coefficients. The stability analysis of the ADSMC is also given in this paper. Simulation and experimental results demonstrate that the proposed characteristic model-based ADSMC can achieve high-precision control over a Michelson interferometer-based FTS. The significant advantages of the proposed ADSMC are its robustness and better control performance over the external disturbance and internal parameter uncertainty of the system. |

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.
