| Abstract | This paper presents design and implementation of a novel adaptive chattering-free sliding mode control (ACFSMC) scheme and its application to motion control of robot manipulators. Due to the presence of complex phenomena such as large flexibility, model uncertainties, and external disturbances a robust and adaptive control is required to control the motion of the robots. This paper presents the design of an adaptive chattering-free sliding mode control using two adaptation mechanism namely: a fast and performance-based online estimation of uncertainties, which is constructed based on the dynamic behaviour of a sliding function; and an adaptive fuzzy model of the robot, which is constructed using a systematic fuzzy modelling method and from input-output data of the robot through system identification. These two adaptation mechanism can be interpreted as the integration of fast response to immediate feedback information and the response based on the knowledge that has already been built into the fuzzy model of the controller, which is the model-based component of the ACFSMC. The global stability and robustness of the proposed controller are established using Lyapunov's approach and fundamentals of sliding mode theory. Based on the simulations and experimental results, the proposed controller performs remarkably well in comparison to SMC with boundary layer and the high gain proportional-integral-derivative (PID) controllers in terms of the tracking error convergence and robustness against uncertainties. |

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.
