| Abstract | In this paper, we propose a coupled sliding-mode control (SMC) method for the periodic orbit generation and the robust exponential orbital stabilization of inverted-pendulum systems. We first design an SMC law to force a coupled sliding surface to be reached in finite time, such that the zero dynamics are generated in the form of a second-order undamped and forced nonlinear differential equation. Through the stability analysis, it is shown that there exist exponentially stable periodic solutions of the resulting zero dynamics (i.e., limit cycles around either the upright or downward equilibrium), even in the presence of the matched disturbance. Second, we design a target orbit stabilization control law by further introducing an auxiliary control law to the designed SMC law. This auxiliary control law utilizes the general integral of the autonomous zero dynamics, which preserves its zero value along the given target orbit, and thus, it can contribute to the exponential stabilization of the general integral. To demonstrate the validity of the proposed method, both the periodic orbit generation and target orbit stabilization control of the cart-pendulum, as an example among inverted-pendulum systems, are performed in numerical simulations. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
