| Abstract | In this paper, we deal with an optimal control problem for nonholonomic systems. We would be confronted with the Hamilton-Jacobi-Bellman (HJB) equation, whenever we try to obtain the feedback solution. Moreover, it is well known that a viscosity solution is necessary for the HJB equations in the case of nonholonomic systems. Generally, it is very difficult to obtain a standard solution for the HJB equations and so it is much more difficult to obtain a viscosity solution. Therefore, in the design methodology for the nonholonomic systems, little research has been reported so far. We introduce an approximation technique for the nonholonomic problems and construct a feedback controller based on the standard solution of the HJB equation, instead of the viscosity solution. Therefore, the existing research results to obtain the standard solution of the HJB equations is usable in our approach. Our control design consists of two steps. First step is to construct a controller using this standard solution. However, it should be noted that the trajectories do not converge to the origin because of the approximation error. Second step is to design a control strategy without performance index in order to let the trajectories converge to the origin from the neighborhood using a characteristic of nonholonomic systems. |

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.
