| Abstract | This paper proposes a new force sensorless impedance control scheme for industrial robot to deal with the industrial robot under impact with environment. With the novel motion control based on D-PD (derivative-PD) and feedforward inverse-dynamic torque compensation, the industrial robot is assured in performing task with accuracy and rapidity. Only stiff servo strategy, however, the robot tends to encounter with difficulties when robot collides with the environment. The proposed observer-based workspace impedance control scheme does well match with the D-PD position control, which uses both position and velocity references to implement the damping and stiffness characteristic of the impedance model. The flexible-joint modeled industrial robot with its robust resonant-suppression motion control and force sensorless impedance control is an adequate platform to implement on the ordinary industrial robot system. Finally, the experimental results of the workspace impedance control performed on the three-degree-of-freedom (3-DOF) robot manipulator confirm the effectiveness of the proposed control scheme. |

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.
