| Abstract | The Time Delay Control with switching Action (TDCSA) method was recently proposed as a promising technique in a robust control area, where a plant has unknown dynamics with parameter variations and substantial disturbances are present. When TDCSA is applied to a nonlinear system with frequency resonances, TDCSA reveals a chattering problem or an undesired vibration. This undesired vibration and chattering problem comes from the switching action and high gains. Fast sliding mode dynamics or fast desired error dynamics improve the control performance, but excite the un-modeled resonance modes and cause an undesired vibration or chattering. To solve this problem, we proposed an integral sliding surface design method using frequency-shaping features. This method incorporates frequency-shaping LQ design techniques into an integral sliding surface. In this paper, the stability analysis of TDCSA using a frequency-shaped integral sliding surface is analyzed. Based on the experimental results, the frequency-shaped integral sliding surface was shown to be practicable for a single-link flexible arm. Motion control of a single-link flexible arm with un-modeled flexible modes was taken into account. The desired trajectory was tracked while minimally exciting the un-modeled flexible modes. |

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.
