Fascinating Applications of Optimal Guidance in Challenging Space Missions

Fascinating Applications of Optimal Guidance in Challenging Space Missions
October 24, 2016 2:30 PM - 4:00 PM AU Auditorium, GICT Building Lectures Series

Dr. Radhakant Padhi, Department of Aerospace Engineering, Indian Institute of Science, Bangalore, delivered the lecture, 'Fascinating Applications of Optimal Guidance in Challenging Space Missions'  at School of Engineering and Applied Science. Following is the abstract of the lecture.


Even though the theory of optimal control is quite fascinating and a great deal of research has been carried out since the time of Bernoulli and Newton, time and again it has been observed that it suffers from either the “curse of complexity” or the “curse of dimensionality”, making it virtually impossible to implement it in real time. However, several pioneering research has been done in last two decades which cuts through these bottlenecks. A variety of innovative ideas and algorithms have appeared in the literature to compute the optimal control history in real time, thereby opening a whole new possibility of limitless applications, especially in aerospace engineering and mobile robotics. Rapid advancement of computing power has also added positively to this cause. The first part of this seminar talk will contain a brief overview of optimal control theory as well as some of the recently-developed algorithms for fast computation of the optimal control history. This will be followed by an overview of a specific algorithm developed and used extensively by the speaker and his co-workers, named as “Model Predictive Static Programming (MPSP)”. Challenging real-life applications for autonomy of space vehicles, namely Autonomous Soft-Landing on Moon, Re-entry Guidance of Reusable Launch Vehicles, Formation Flying of Satellites and Autonomous Docking will be part of this keynote lecture.
