| Abstract | This paper investigates a new method for tracking parameters at which dynamic bifurcations occur in MEMS based on state statistics of a resonator. Experimental results show that observed changes in phase and amplitude precede a sub-critical pitchfork bifurcation. Feedback control, based on the statistics of the phase, is then employed to stabilize a device on the edge of instability. Sensitivity to changes in device parameters is explored and initial results show high sensitivity is obtained for low vibration amplitudes. Furthermore, experimental results on the same device using an older method of bifurcation sensing show acquisition rate improvement by over three orders of magnitude with the new method. |

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.
