| Abstract | A hydraulic servo system has nonlinearity and uncertain dynamics, so its theoretical mathematical model can't sufficiently represent the practical system. The identification experiments were carried out in hardware-in-the-loop simulation environment and the identification model was acquired. In order to improve the tracking performance of the force servo system a new nonlinear hybrid controller was developed composed of a classical PID controller and a fuzzy controller based on self-adjusting modifying factor, which was added feedforward compensation. A fuzzy switching mode was employed to avoid the undesirable disturbances caused by the switchover between the two control methods. By simulations and experiments on an electro-hydraulic servo test bench the feasibility of the control scheme was validated by comparison with a PID and a conventional fuzzy control. The research results show that the hybrid PID controller improves stability and rapidity when load rigidity and mass changed, and has good performances in real time applications. |

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.
