| Abstract | A polishing implementing mechanism control system of a large freeform surface polishing robot is designed in this paper. According to the structure characteristic of the implementing mechanism, the control process is composed of position control process and pressure control process. The control system has overcome nonlinear characteristic of the proportional reducing valve effectively and ensured the implementing mechanism can start quickly by using the position and pressure closed loops. For the purpose that the robot can polish on a large freeform surface, a mathematic model of valve control cylinder system is established. The factor of influencing polishing pressure is analyzed. The PID control algorithm is used into the system with the position and pressure of cylinder as the signal of feedback. The experiments prove that this control system can achieve constant pressure polishing while the robot polishes with a certain velocity. |

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.
