Control Challenges for the Laser Interferometer Gravitational-wave Observatory (LIGO)
Dennis Coyne, LIGO Laboratory at the California Institute of Technology

Tuesday June 30, 2020 at 6:15 PM in Ballroom DE

Abstract: In September 2015, the Laser Interferometer Gravitational-wave Observatory (LIGO) initiated the era of gravitational wave astronomy (a new window on the universe) with the first direct detection of gravitational waves (ripples in the fabric of space-time) resulting from the merger of a pair of black holes into a single larger black hole. In August 2017 the LIGO and VIRGO collaborations announced the first direct detection of gravitational waves associated with a gamma ray burst and the electromagnetic emission (visible, infrared, radio) of the afterglow of a kilonova — the spectacular collision of two neutron stars. This marks the beginning of multi-messenger astronomy. The kilonova discovery was made using the U.S.-based LIGO; the Europe-based Virgo detector; and 70 ground- and space-based observatories.

The Advanced LIGO gravitational wave detectors are second generation instruments designed and built for the two LIGO observatories in Hanford, WA and Livingston, LA. These two identically designed instruments employ coupled optical cavities in a specialized version of a Michelson interferometer with 4 kilometer long arms. Resonant optical cavities are used in the arms to increase the interaction time with a gravitational wave, power recycling is used to increase the effective laser power and signal recycling is used to improve the frequency response. In the most sensitive frequency region around 100 Hz, the displacement sensitivity is 10^-19 meters rms, or about 10 thousand times smaller than a proton. In order to achieve this unsurpassed measurement sensitivity Advanced LIGO employs a wide range of cutting-edge, high performance technologies, including an ultra-high vacuum system; an extremely stable laser source; multiple stages of active vibration isolation; super-polished and ion milled optics, high performance multi-layer dielectric coatings; wavefront sensing; active thermal compensation; very low noise analog and digital electronics; complex, nonlinear multi-input, multi-output control systems; a custom, scalable and easily re-configurable data acquisition and state control system; and squeezed light. The principles of operation, the numerous control challenges and future directions in control will be discussed.

Biography: Dennis Coyne is the Chief Engineer for the LIGO Laboratory at the California Institute of Technology (Caltech) in Pasadena, California. Over the last 24 years he has led the LIGO engineering team’s efforts in design and implementation of first and second generation instruments. The Laser Interferometer Gravitational-wave Observatory (LIGO) is a first of its kind instrument, capable of measuring the sub-atomic stretching of space due to cataclysmic cosmological events. The LIGO founders were awarded the Nobel Prize in Physics in 2017 for the direct detection of gravitational waves which were predicted by Albert Einstein. LIGO is now an operating observatory enabling multi-messenger astronomy. Prior to joining Caltech, Dennis worked for Kaman Sciences Corp. and Bell Laboratories. Dennis received a BSME from UMass and an MSME from UC Berkeley. He is a fellow of the ASME, a fellow of the APS, recipient of the 2018 AAS Lancelot M.

Lots to be Done: Towards Data-informed, Real-time Coordination Algorithms that Scale Up
Sonia Martinez, University of California, San Diego

Wednesday July 1, 2020 at 8:00 AM in Ballroom ABC

Abstract: Networked and robotic systems in emerging applications are required to operate safely, adaptively, and degrade gracefully while coordinating a large number of nodes. Distributed algorithms have consolidated as a means for robust coordination, overcoming the challenges imposed by the limited capabilities of each agent. However, plenty of problems still exist to break down the barriers of fast computation, make effective use of measured data, and understand large-scale limit effects. In this talk, I will present ongoing work in the control of infrastructure networks and large-swarm coordination, along with a discussion on modeling approaches, analysis tools, and architectural trade-offs going from small to large-sized robotic networks.

Advances and Opportunities of AI and Machine Learning in Industrial Process Monitoring and Control
Leo H. Chiang, Dow, Inc.

Wednesday July 1, 2020 at 6:15 PM in Ballroom ABC

Abstract: To ensure safety, reliability, and productivity of industrial processes, artificial intelligence (AI) and machine learning techniques have been widely used in process industries for decades.    The benefits of process monitoring and control are well documented and employed routinely in manufacturing.  This talk will go over historical perspective and recent AI and machine learning successes in the areas of real-time analytics, deep learning, reinforcement learning, visualization, and feature engineering.  Complex interaction between human decision and automated control will be discussed.    Humans grow expertise by quickly adapting to abnormal conditions and using domain knowledge to generate creative solutions.  However, reproducing human decisions across the enterprise is a challenge.  A common misconception is that AI is to replace human decision.  The talk will emphasize how AI and control systems must be complementary to make human decisions as efficient and consistent as possible.  Human decision will remain a center piece of how to operate industrial processes in a safe, reliable, and productive manner.

Control of Complex Energy and Power Systems for Electrified Mobility
Andrew Alleyne, University of Illinois, Urbana-Champaign

Thursday July 2, 2020 at 8:00 AM in Ballroom ABC

Abstract: Electrification of mobility and transport is a global megatrend that has been underway for decades. The mobility sector encompasses cars, trucks, busses and aircraft. These systems exhibit complex interactions of multiple modes of power flow.  These modes can be thermal, fluid, electrical, or mechanical.  A key challenge in working across various modes of power flow is the widely varying time scales of the subsystems which makes centralized control efforts challenging.  This talk will present a particular distributed controller architecture for managing the flow of power based on on-line optimization.  A hierarchical approach allows for systems operating on different time scales to be coordinated in a controllable manner. It also allows for different dynamic decision making tools to be used at different levels of the hierarchy based on the needs of the physical systems under control. Additional advantages include the modularity and scalability inherent in the hierarchy.  Additional modules can be added or removed without changing the basic approach.

In addition to the hierarchical control, a particularly useful graph-based approach will be introduced for the purpose of modeling the system interactions and performing early stage design optimization. The graph approach, like the hierarchy, has benefits of modularity and scalability along with being an efficient framework for representing systems of different time scales.  The graph allows design optimization tools to be implemented and optimize the physical system design for the purpose of control.  Recent results will be presented representing both generic interconnected complex systems as well as specific examples from the aerospace and automotive application domains.

Title: Distributed Decision Making in Network Systems: Algorithms, Fundamental limits, and Applications
Na Li, Harvard University

Friday July 3, 2020 at 8:00 AM in Ballroom ABC

Abstract: Recent radical evolution in distributed sensing, computation, communication, and actuation has fostered the emergence of cyber-physical network systems. Examples cut across a broad spectrum of engineering and societal fields. Regardless of the specific application, one central goal is to shape the network collective behavior through the design of admissible local decision-making algorithms. This is nontrivial due to various challenges such as the local connectivity, imperfect communication, model and environment uncertainty, and the complex intertwined physics and human interactions. In this talk, I will present our recent progress in formally advancing the systematic design of distributed coordination in network systems. We investigate the fundamental performance limit placed by these various challenges, design fast, efficient, and scalable algorithms to achieve (or approximate) the performance limits, and test and implement the algorithms on real-world applications.
