| Abstract | Human beings to face with oil and coal depletion of fossil fuels. With the development of society, energy saving and environmental protection have become a topical issue. The sun energy using is in the rapid development and application; however, the amount of power produced by a sun tracker depends upon the amount of sun light. This paper proposes a fuzzy sliding-mode controller (FSMC) with a time-varying sliding surface to control a light tacking system via the sliding-mode control approach. The proposed FSMC system is composed of a fuzzy controller and a slope regulator. The fuzzy controller infers the control action to control the system states to reach the sliding surface without large overshoot, and the slope regulator tunes the slope of the sliding surface to govern small convergence time of the system trajectories. Thus, the proposed FSMC system can achieve satisfactory tracking performance with fast transient response and good robustness. Finally, the proposed FSMC system is implemented based on a field programmable gate array chip for low-cost and high-performance industrial applications. The experimental results show the proposed FSMC can achieve favorable tracking performance for the light tracking system even under a payload onto the platform of the light tracking 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.

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.
