| Abstract | This paper addresses the design problem of practical (or satisfaction) adaptive output-feedback tracking control for stochastic strict-feedback nonlinear uncertain systems in observer canonical form with stable zero-dynamics under long-term average tracking error risk-sensitive cost criteria. The cost function adopted here is of quadratic-integral type usually encountered in practice, rather than of quartic-integral one commonly used to avoid difficulty in control design and performance analysis of the closed-loop system. A sequence of coordinate transformations are first introduced to separate the zero-dynamics from the entire system so that the transformed system has an appropriate form suitable for observer design and integrator backstepping design. Then, for any given risk- sensitivity parameter and desired cost value, by using the integrator backstepping methodology, an adaptive output-feedback tracking control is constructively designed such that (a) the closed-loop system is bounded in probability and, (b) the long- term average risk-sensitive cost is upper bounded by the desired value. Among others, this paper does not require the uniform boundedness of the gain functions of the system noises. This paper can be regarded as the further research of [21]. |

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.
