| Abstract | Super-articulated mechanical systems tems have more degree of freedom than actuators. For these systems, the relationship between actuator inputs and configuration space trajectories in nonholonomic in the sense that when the input variables return to their initial values it will not generally be the case that configuration variables also return to the initial values. Ih this paper, the long-term effects produced by periodic forcing of super-articulated mechanical systems are studied. For a certain class of Lagrangian control systems with symmetry, it is shown that the stability of equilibrium motions may be assessed in terms of a quantity which we call the averaged potential. For systems in which there is great complexity in the periodically forced dynamics (for instance in the rotating kinematic chains studied in [2] and [4]), appears to afford an attractively simple approach. The method is illustrated in solving the classical problem of stabilising an inverted pendulum by forced vertical oscillation of the point of suspension. |

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.
