| Abstract | Existence of the long pipeline in hydraulic system will worsen the system dynamic performance. Aiming to acquire a simple control system model, a mass-damping dynamic model was used to simulate pipeline element by analyzing kinetic feature and physical properties of fluid in pipeline, and pipeline transfer function was derived. Mathematic model of position control of valve controlled asymmetric cylinder was established, and the high order plant was disposed to be second-order model with time delay in frequency domain. A PI-PD-Smith predictor was designed, and the parameters of controller were optimized according to integral time absolute error (ITAE) optimization criterion. The system with PI-PD-Smith predictor and conventional Smith predictor was compared by simulation. The result shows that PI-PD-Smith predictor has better control quality than conventional Smith predictor for position control of electro-hydraulic servo system with long pipelines. |

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.
