Abstract | We present the design of a robust sliding mode controller for the force control of a hydraulic actuator in presence of significant system nonlinearities and uncertainties. Our control strategy is based on sliding mode control. The design of a switching surface is based on Lyapunov techniques, and a variable structure control law is designed using the theory of sliding mode control. For the control we use a nonlinear mathematical model of a hydraulic system interacting with the environment. We try and consider most of the nonlinear and uncertain dynamics of this system in order to achieve robust performance over a range of operating conditions. The simulation results show that the proposed sliding mode controller is not sensitive to a large variation of parameters such as flow gain, supply pressure or environmental stiffness, and has an excellent tracking performance for various set point forces under uncertainties. |

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.
