Abstract | In this paper, the parameter robust design method and sliding mode control theory are combined to design the helicopter control system in the whole flight envelop with the uncertainties and nonlinearities considered. First based on the flying qualities and the constraint conditions of the measurable states, the partial pole assignment is realized by the parameter robust design method, accordingly the mapping relationship of the parameter space and the corresponding usable set is determined, which provides an effective method to design the equivalent scheduling control law in the whole flight envelop. Second based on the helicopter T -S model within the whole flight envelop, according to the parameter mapping law, the equivalent control law is designed using the parallel distributed compensation algorithm, which ensures the well dynamic performance the control system in the whole flight envelop. Finally the closed-loop system characteristic equation corresponding to the equivalent control law is used to construct the integral sliding surface. The switching is designed so that the system has the robustness against the uncertainties and disturbances. The simulations indicate that the proposed sliding mode control system is robust against the external disturbances, it has the strong disturbance-suppression capability and satisfies the dynamic performance requirements of the helicopter. |

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.
