| Abstract | In everyday life environments, various disturbances like pushing or pulling forces may cause humanoids to fall. Thus, they should be able to quickly adapt to disturbances. Model predictive control is a general control scheme which can generate the online motions need to be realized to act efficiently against disturbances. In this paper the model predictive control is used to address the problem of online compensation of the external disturbances exerted to a biped robot. This is accomplished using a three dimensional linear inverted model of the robot in combination with model predictive control scheme. Several simulations have been done considering wide range of the push forces exerted in the Single Support Phase (SSP) and Double Support Phase (DSP) of the walking cycle. Design parameters of the MPC such as control and prediction horizon and constraints on the manipulating variable are adjusted to improve the results. Simulation results demonstrate the effectiveness of the method to compensate the disturbances both in SSP and DSP. |

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.
