Talk title: Infrastructure Enabled Autonomy - A New Paradigm for Autonomy as a ServiceSpeaker: Swaminathan Gopalswamy
Abstract: Multiple studies have illustrated the potential for dramatic societal, environmental and economic benefits from significant penetration of autonomous driving. However, all the current approaches to autonomous driving require the automotive manufacturers to shoulder the primary responsibility and liability associated with replacing human perception and decision making with automation, potentially slowing the penetration of autonomous vehicles, and consequently slowing the realization of the societal benefits of autonomous vehicles. This talk will present a new approach to autonomous driving that will re-balance the responsibility and liabilities associated with autonomous driving between traditional automotive manufacturers, private infrastructure players, and third-party players. The proposed distributed intelligence architecture leverages the significant advancements in connectivity and edge computing in the recent decades to partition the driving functions between the vehicle, edge computers on the road side, and specialized third-party computers that reside in the vehicle. Infrastructure becomes a critical enabler for autonomy. A Bayesian Network Model based framework for assessing the risk benefits of such a distributed intelligence architecture will be discussed. Results from preliminary, on-going research in developing a concept proof of IEA will be discussed also.
Bio: Swaminathan Gopalswamy, Professor of Practice and Director of the Connected Autonomous Safe Transportation (CAST) Program at the Department of Mechanical Engineering, Texas A&M University, College Station. He is the founder and CEO of Engineered Mechatronics, Inc., a company looking at bringing the latest advances in controls and software engineering to the mechatronics systems development process. Prior to this, he was an LMS-Vice President of Controls at Siemens PL, which had acquired LMS International, where he was a VP of Model Based Systems Engineering. LMS, in turn, had acquired Emmeskay Inc., which he had co-founded and was an advanced technology solution provider focused on the automotive industry. He obtained his B.Tech. from the Indian Institute of Technology Madras, and his M.S. and Ph.D. (1991) from the University of California, Berkeley. His expertise is in Nonlinear system dynamics and control, Model Based Systems Engineering, Model Based Control System Design, Simulation based verification and validation, Powertrain architecture optimization for performance and fuel economy. He has worked on automotive systems modeling, simulation and optimization for over twenty five years.
Swaminathan Gopalswamy Education : Ph. D. 1991 – Mechanical Engineering, University of California, Berkeley. “Adaptive Control of Nonlinear Non-minimum Phase Systems”. One key contribution was a methodology to address the impact of unstable zero-dynamics of nonlinear systems (i.e. non-minimum phase systems) when doing input-output fee dba ck l i nea r i za ti on . An “ideal internal dynamics” that is a subset of possible solutions on the manifold corresponding to the zerodynamics is identified. Then an output redefinition is proposed that renders the actual internal dynamics stably converging to the ideal internal dynamics, while simultaneously rendering the actual output converging to the desired trajectory. This methodology could then be directly extended to robust nonlinear techniques such as sliding control. A second contribution was the extension of the robust control above to include adaptation of a class of parametric uncertainties for Multi-Input-Multi-Output Nonlinear systems. Thesis Advisor: Prof. J. Karl Hedrick M.S. 1989 – Mechanical Engineering, University of California, Berkeley. “Longitudinal Control of High Performance Aircraft” High Performance aircraft have highly nonlinear dynamics, are statically unstable, and in fact exhibit non-minimum phase behavior. The focus of this effort was to develop a strategy to control the longitudinal dynamics of the aircraft to pull “high g's” coordinated with the pitching. This was achieved by re-defining the location of calculation of the g's from the c.g. of the aircraft to the pilot location. This intuitive approach was subsequently generalized as part of the PhD thesis. B.Tech 1987 – Mechanical Engineering, Indian Institute of Technology, Madras (Chennai), India. “Design and Build of an RCR 0 CR (3D crank-rocker) mechanism for maximum rock angle” Work Experience : June 1991 – Dec 1991 – Integrated Motions Inc, Berkeley, CA.
