| Abstract | The purpose of this paper is to investigate the trajectory tracking problem of the mobile robot. The method integrates a kinematic controller and a torque controller into the dynamic model using backstepping techniques. First, the analytic B-spline function is used to generate a smoothly feasible trajectory between the initial and desired configuration so that the motion path can pass through desired intermediate points and satisfy the kinematic constraints and curvature restrictions. Second, a set of sufficient conditions and a systematic transform procedure are presented for determining if a nonlinear kinematic model can be converted to the integrator chained form which significantly reduced the complexity of designing the privileged velocity. Finally, an adaptive tracking control is developed for the hierarchical model based on backstepping methodology and computed-torque techniques to achieve global asymptotically stable. Simulation results are utilized to illustrate the effectiveness of the proposed control architecture. |

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.
