A variety of interesting and useful applications are possible in satellite formation flying missions, both as a substitute to single large satellite missions as well as the ones unique to the formation flying missions. Wide-area and/or frequent Earth observation for remote sensing and monitoring geographic regions of interest, telescopic formation for solar or deep space observation, computer tomography of clouds etc. are a few examples. To derive maximum benefits from the formation flying of spacecraft, it is necessary to guarantee the intended formation with minimum deviation under the realistic scenarios such as elliptic orbits and in the presence of disturbance forces such as the J_2 gravitational perturbation. To achieve this ambitious objective, powerful guidance laws based on advanced nonlinear and optimal control theory are the need of the hour. The seminar talk will discuss several such techniques, followed by summarizing their relative merits, and providing some insightful recommendations under various scenarios. In fact, the seminar will briefly expose the audience about the topics covered in one of the recently published books of the speaker along with his co-author.

He is an Associate Fellow of AIAA and a Senior Member of IEEE. He is a member of the Technical Committee on Aerospace in both IEEE and IFAC and a vice-chair of the publication board of IFAC. During 2014-2020 he was a member of the IFAC Council. He was also a member of the Board of Governors of IEEE Control System Society in 2020. He is the Director of Operations of the Automatic Control and Dynamic Optimization Society of India and has been a past president of it too. He is a Steering committee member of the Asian Control Association during 2016-2021. He is a life member of Soft Computing Research Society, Aeronautical Society of India, and Systems Society of India. He is an Associate Editor of three international journals in the control and automation field.

Dr. Padhi’s research interest is on optimal and nonlinear control synthesis algorithms and their applications to challenging practical problems in aerospace, biomedical and mechanical engineering. He has co-authored over 260 publications in international journals and conferences, and a book on Satellite Formation Flying. His research is well-supported by Ministry of Human Resource Development (MHRD) of the Govt. of India, Defence R&D Organisation (DRDO) of India, Indian Space Research Organisation (ISRO), Air Force Research Lab (AFRL) of USA, Agency for Defence Development of South Korea etc.

Currently his research group is passionately involved in (i) Soft-landing of spacecrafts on Moon and Mars, (ii) Long-duration station-keeping and robust attitude control of spacecrafts on Halo orbits, (iii) Dynamic modelling and optimal management of air-traffic over the Indian airspace, (iv) intelligent guidance and control of UAVs, and (v) Developing an artificial pancreas system for Type-1 diabetic patients of India.
