| Abstract | Vertical take-off and landing (VTOL) aircraft system is a non-linear complex system with multi-variable large-disturbances. Hence it is a difficult task to control it efficiently. For the first time, this study applies the most advanced kernel-based dual heuristic programming (DHP) algorithm into solving the optimal control problems of VTOL aircraft systems successfully. Kernel-based DHP (KDHP) algorithm is developed by integrating sparse kernel machines and approximately linear dependence analysis into the critic learning of DHP algorithm. Kernel machines are used as approximation structure for the critic module in the proposed KDHP algorithm, while multilayer perceptron neural networks (MLPNNs) are used as approximation structure for conventional DHP algorithm. Compared with conventional MLPNNs with manually designed structures, kernel method can obtain better generalisation capability. Hence to a certain extent, the proposed KDHP algorithm has better learning efficiency and generalisation capability. Moreover, the simulation and experimental results of VTOL aircraft system control problems demonstrate that the optimal controller based on the proposed KDHP algorithm is effective. |

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.
