| Abstract | Controlling complex systems, containing nonlinearities and constraints, is always a domain of interest for researchers. Different schemes such as Nonlinear Model Predictive Control (NMPC) have been proposed but these are usually computationally demanding and complex by themselves. Nowadays two powerful techniques, Fuzzy Modeling and Model Predictive control, are being blended together in different ways to attain the advantages of controlling delayed, non-minimum phase, nonlinear and constrained systems efficiently. The paper discusses this novel technique to control a class of nonlinear systems, the Hammerstein models. In order to control the Hammerstein model containing static nonlinearity with linear GPC algorithm a $0^{th}$ order TS adaptive fuzzy inverse model controller is used with feedback. This strategy makes the scheme powerful enough to be used with different Hammerstein models containing different types of static nonlinearities and different linear dynamics. Furthermore the GPC algorithm is developed by using Toeplitz/Hankel matrices rather than Diophantine equation to reduce computational complexity. The scheme has been tested in MATLAB/Simulink for different kinds of nonlinearities and different parameters of system dynamics, and has produced good control results. Simulation results show that in any case, the optimization remains convex and single layer of optimization is sufficient to optimize the cost function. |

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.
