| Abstract | Layered neural networks are used in nonlinear adaptive control problems. Both the discrete-time case and the continuous-time case are considered. For the discrete-time case, the plant is an unknown SISO feedback-linearizable discrete-time system with general relative degree, represented by an input-output model; a state space model of the plant is obtained. This model is used to define the zero dynamics, which are assumed to be stable. A layered neural network is used to model the unknown system and generate the feedback control. Based on the error between the plant output and the model output, the weights of the neural network are updated. For the continuous-time case, we work on a SISO relative-degree-one system with zero dynamics, and on a MIMO general relative degree system without zero dynamics. The neural network is used to model the nonlinear functions of the continuous-time systems, instead of modeling the whole system as in the discrete-time case; and the control law for the continuous-time case does not involve an explicit system identification process, as appears in the discrete-time case. The convergence results obtained for both cases are regional in state space, yet local in parameter space. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
