| Abstract | We introduce a dual input Parallel Force/Velocity Actuation (PFVA) concept in this paper to enable variable response manipulation. The objective of this paper is to develop an analytical model for power flow in PFVA systems. We studied the functional dependence of external and internal power flow phenomena on two dimensionless parameters we define in this paper, namely Relative Scale Factor (ρ) and Velocity Mixing Ratio (λ). We observed that overall mechanical efficiency of the PFVA decreases approximately 16% from the basic efficiency when the RSF was increased 5x and the VMR was increased 10x. For a specified load torque of −100 Nm at the output of a positive-ratio PFVA and a fixed VA angular velocity of 150 RPM, the Futile Power Ratio (FPR) was observed to increase by approximately 40% when the RSF was increased by 5x and the FA velocity was increased from 0–80 RPM. Based on our analytical development we suggest some design and operational guidelines for PFVA based 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.
