| Abstract | The vertical motion control systems and robust two-degree-of-freedom (2DOF) control for high rise/high speed elevators are discussed in this paper. The control aim is that under the desired control performance realizes robust tracking and releveling control and let the system have good robustness for uncertainties. A kind of robust 2DOF control method is proposed for elevators on the basis of vertical motion control description. This method can reject effectively the affect of parameter variation for system and the good tracking characteristic, disturbance rejection characteristic, robustness and high precision releveling performance can be achieved simultaneously. First, the design of speed controller is converted into a standard Hinfin control problems. Second, with the help of LMI approach, a output feedback sub-optimal Hinfin controller is obtained. Finally, an Hinfin optimal controller is gained by solving a convex optimization problem so as to guarantee system robustness. The simulation results show that this method 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.
