| Abstract | A boiler-turbine unit is a typical multi-input multi-output (MIMO) industrial control system in power plant, which has nonlinear and couple characteristics. In this paper, a constrained dynamic matrix control (DMC) algorithm is designed for a nonlinear multivariable boiler-turbine unit with hard input constraints. Firstly an improved unconstrained DMC algorithm based on step response model for a single-input single-output (SISO) integrating process is proposed. It is shown that the proposed algorithm is more effective than conventional DMC and can also be extended to MIMO systems with integrating subsystems and input/output constraints. A 1-norm objective function is presented and the control actions can be obtained using linear programming online. Simulation results show that the designed control system has good tracking property and disturbance rejection ability without steady state offset while the control actions satisfy the constraints |

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.
