Abstract | In this paper a feedback linearization (FL) and extended state observer (ESO) based control law is proposed for the trajectory tracking control of a flexible joint robotic system. The FL based controller requires the transformed full state vector for its implementation. The design also requires exact knowledge of the system model making the controller performance sensitive to uncertainties. To address these issues, an ESO is designed which estimates the state vector as well as the uncertainties in an integrated manner. The FL controller uses the states estimated by ESO and thus the issue of availability of the states is addressed. Further the effect of uncertainties is compensated by augmenting the FL controller with the ESO estimated uncertainties. The effectiveness of the ESO in estimation of the uncertainties and states and tracking performance of the augmented controller are demonstrated through simulation. |

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.
