Abstract | This paper investigates the modeling and control problem of a novel piezoelectric-actuator (PZT) driven nanopositioner. The physical model of the nanopositioning stage is first discussed with the hysteresis nonlinearity of the PZT actuator. For the purposes of eliminating the hysteresis impact and various disturbances, an active disturbance rejection control (ADRC) algorithm is proposed, where the nonlinear dynamics of the model and external disturbances are treated as “total disturbances” which can be estimated by an extended state observer (ESO) and then compensated by a state feedback control law. The proposed algorithm is deployed in real time implementations on a nanopositioning servo platform and demonstrates good control performance in terms of high precision positioning and hysteresis elimination. |

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.
