| Abstract | By the use of flatness the problem of pole placement, which consists in imposing closed loop system dynamics can be related to tracking. Thus point of view has been used to enlighten the design of RST controllers in the linear system case with constant parameters. We will see in the present paper that in the case of time-varying linear systems thus point of view can also be adopted and leads to design a feedback in terms of the flat output and its derivatives. To implement this feedback a constant gain reduced order observer can be used. The observer poles are also chosen with respect to the trajectory to follow. All these developments are exemplified on a DC motor with a time-variant stator flux, and lead to a simple but powerfull control for tracking a given trajectory for the angular velocity of the motor. |

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.
