Title: Controller Design for a Virtual Skydiver and its Modelling and Verification
Presenter: Prof. Per-Olof Gutman (Technion- Israel Institute of Technology, Haifa, Israel)
Abstract: The speaker will present an innovative approach of gaining an insight into motor skills involved in human Body-flight. Body-flight is the art of maneuvering during the free fall stage of skydiving, which is a rapidly developing sport. The key idea is creating an autonomous system capable of performing skydiving maneuvers in a virtual way, and turning it into a powerful tool for improving instruction methods. Towards this goal, the Skydiver Simulator is developed, comprising Biomechanical, Aerodynamic, and Kinematic Models, Dynamic Equations of Motion, and a Virtual Reality Environment. A Two-Input-Two-Output controller is designed to track the desired inertial motion, producing commands in terms of limbs movements. The natural kinematic redundancy of the human body is resolved by introducing movement patterns, constructed according to ergonomic considerations and empirical knowledge of how skydiving maneuvers are performed. The controller is designed with the use of Quantitative Feedback Theory, providing robustness for dealing with plant non-linearities and inaccurate execution of the movement patterns. The skydiver simulator allowed reconstruction of many challenging aspects of body-flight observed by practicing skydivers. The virtual skydiver, comprising a controller and a guidance algorithm, was shown to autonomously perform meaningful body flight missions.

Bio of the speaker: Prof. Gutman received the Ph.D. in Automatic Control (1982) and the title of Docent in Automatic Control (1988) from the Lund Institute of Technology, Lund, Sweden. 1984-1990 he was a scientist with the Control Systems Section, El-Op Electro-Optics Industries Ltd, Rehovot, Israel. From 1989 he is with the Technion – Israel Institute of Technology, Haifa, Israel, holding, since 2007, the position of Professor at the Faculty of Civil and Environmental Engineering. 2016-2018 he held the Beatrice Sensibar Chair in Environmental Engineering, and since 2018 he is Professor Emeritus. His research interests include robust and adaptive control, control of complex non-linear systems, computer aided design, vehicle control, including autonomous vehicle control, and traffic control. He invented the Vertex Control control method (with M. Cwikel), and its extension Interpolating Control (with Hoai-Nam Nguyen, Sorin Olaru, and Morten Hovd). Gutman has (co-)authored over 90 papers for reviewed international journals, has contributed to 6 books, and co-authored Qsyn – The Toolbox for Robust Control Systems Design for use with Matlab.
