| Abstract | Dissimilar redundant actuation system has high reliability because of getting rid of central hydraulic power and avoiding common cause failures, which conform to the development trend of future actuation systems in large civil aircraft. Despite these advantages, force fighting widely exists in dissimilar redundant actuation systems due to the different driving principle and system parameters of different actuators. All these factors can affect output precision, shorten operation life, or even lead to system failure. To cope with this problem, this paper proposes a new adaptive decoupling controller based on motion state synchronization. The parameter adaption law is designed for the parametric uncertainties in the dissimilar redundant actuation system and motion state synchronization is proposed to deal with the differences between two different actuators. The comparative simulation results between the proposed algorithm and traditional method indicate that the proposed synchronous controller is capable of achieving better tracking control performance and effectively solving the force fighting problem between different actuators. |

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.
