| Abstract | External excitations of oscillations which are caused by wind and waves are the main sources for disturbances in the task of load positioning by means of ship-mounted cranes in marine applications. These disturbances can be described with good accuracy by stochastic models. Although methods for the stability analysis of dynamic systems, which are subject to stochastic disturbances, are readily available, they are not widely used in practical applications. Instead, a control design is often performed for a nominal system model, while its robustness is commonly evaluated separately by numerous simulations (e.g. Monte-Carlo techniques) aiming at a quantification of the influence of disturbances. For this reason, methods are presented in this paper which are both applicable to the stability analysis of control and observer structures for ship cranes and to the enhancement of robustness properties by directly accounting for the stochastic nature of disturbances during control design. Suitable simulation results are presented which highlight the applicability of the presented methods for the trajectory control task of ship-mounted boom cranes. |

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.
