Abstract | This paper presents an application of an adaptive neuro-fuzzy controller for compensating friction and disturbance effects on robot manipulators. The frictions and disturbances are important parts of the dynamic system of a robot manipulator. However, they are highly nonlinear and not easily modeled. Feedback linearization control combined with PD type fuzzy control and adaptive neural network control are proposed to control robot manipulators with unmodeled frictions. The feedback linearization control is designed to control the trajectory of the robot manipulator while the PD type fuzzy control is added as a parallel controller to control frictions and disturbances. This fuzzy control ensures that good tracking control is maintained even if some modeling error, disturbance, noises exist. The neural network can also be trained with experimental data for the frictions and disturbances. Simulations show that the joint positions are well controlled under wide variation of operation conditions and existences of 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.
