| Abstract | Since communication time delay is a serious problem for bilateral control systems, a great number of researches about delay compensation in bilateral teleoperation with time delay have been studied so far. Some of delay compensators are designed to eliminate phase lag of feedback control and applicable to 4ch-controllers. However, the desired results are not always obtained, even though those compensators are applied to the conventional bilateral 4ch-controller with time delay. This is because these compensators do not take force controllers into account. This paper presents a bilateral 4ch-controller that delay compensators are applied to by considering the force controllers. The proposed controller is designed to control both position and force of a master robot and a slave robot by using only 2 degrees of freedom (DOF). One DOF is utilized for position control, and the other is utilized for force control. Therefore, the position controller and the force controller are shared by the master and slave robots. If delay compensators are applied to the proposed bilateral controller, position and force responses of the master robot correspond with those values of the slave robot, respectively. The validity of the proposed method is verified by simulation and experimental results. |

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.
