| Abstract | In this paper heavy-duty hydraulic crane automation is addressed by applying the Virtual Decomposition Control (VDC) approach. The VDC approach allows the control problem of the entire system to be converted into the control problem of individual components, i.e. subsystems while rigorously guaranteeing the stability of the entire system without jeopardizing the control performance. The experimental results demonstrate that the VDC approach is applicable to robust and high performance control of low-cost hydraulic multi Degree of Freedom (DOF) applications, in which the controller is challenged by a significant number of different nonlinearities and parameter uncertainties. When a VDC controller was compared with a conventional PID controller, approximately 7 times lower piston position maximum error was achieved. Moreover, a VDC controller was given roughly the same control accuracy with low, medium and high velocity trajectory references without any additional tuning, whereas the performance of the PID controller significantly changed between different velocity trajectories. The achieved results with the VDC controller are comparable with the reported state-of-the-art studies on nonlinear model-based control of hydraulic multi DOF 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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
