| Abstract | In this paper a control law which consists of a fuzzy logic controller plus a nonlinear effects negotiator for a flexible robot manipulator is presented. The nonlinear effects negotiator is used to enhance the control system's ability in dealing with the uncertainty of the mathematical model. The control algorithm is simple and easy to tune as opposed to conventional control law which requires time consuming gains selections. To obtain fuzzy control rules, an error response plane method is proposed. This method is mainly based on mathematical reasoning. In addition, the degree of overlap of membership functions for fuzzy rules is investigated. The optimal overlap of membership functions that results in the best performance of the robot is obtained. Moreover, the nonlinear effects of a typical robot motion, such as friction, backlash and external disturbances, are simulated by a sine function with randonmized amplitude and phase in the motion simulation. The results show that the proposed control scheme is robust in that it can cope with modeling uncertainty, nonlinearity, and disturbances due to payload variations simultaneously. |

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.
