Available in PDF, EPUB and Kindle. Book excerpt: Reinforcement learning (RL) has emerged as a front-runner in the race to imbue machines with artificial intelligence, driven by advances in parallel computing hardware, deep neural network architectures, and large data sets. Simultaneously, advances in actuator and sensor technology have brought about platforms with enormous potential to automate menial, dangerous, and expensive tasks such as autonomous driving. As RL leaps from virtual to physical environments, a new challenge appears: safety becomes far more critical. Despite uncertainty about the effects of decisions, which is always present due to noise, errors, and changing environments, control policies must nonetheless direct the evolution of the system towards the goal and away from danger. The fundamental goal of this dissertation is to realize the potential of RL in modern complex systems, contending with challenges posed by dynamics and feedback in the face of uncertainty, by establishing performance and safety guarantees. Despite rapid recent progress, there is still a large gap between theory and practice for optimal control of even relatively simple dynamical systems affected by randomness whose dynamics and statistics are unknown. As a steppingstone towards analysis of more complicated systems, this dissertation focuses on linear systems with multiplicative noise, a stochastic system representation with several practical applications, and linear quadratic control tasks for such systems, useful baselines for which optimal policies can be efficiently computed. This dissertation begins by establishing fundamental connections between stochastic stability and robust stability, formally demonstrating the utility of multiplicative noise as a tool for inducing robustness to parametric uncertainty in dynamic models. Building on this motivating result, RL algorithms across the model-based / model-free continuum that learn optimal policies only from observed data, without explicit access to dynamics or noise statistics governing the system, are developed and analyzed. First, modelfree policy optimization methods, which directly tune policy parameters, are proved to converge at a linear rate with quantified sample complexity polynomial in problemdependent quantities, and can, with appropriate regularization, achieve actuator and sensor sparsity for economical control of networks without sacrificing stability or performance. Second, approximate dynamic programming methods, which have mixed modelfree/based character and learn intermediate value functions, are shown to achieve a fast cubic rate of convergence with a novel midpoint formulation, and obtain policies with enhanced robustness properties when applied to stochastic dynamic games. Third, modelbased system identification methods, which estimate a dynamic model, are proved to learn the dynamics and noise statistics of multiplicative noise systems with quantified error that scales inversely with the square root of the amount of observed data, and are incorporated into adaptive control schemes that obtain robustness against actual uncertainty accrued from model estimation errors. To tractably generate safe trajectories, which are tracked by these data-driven policies, motion planning techniques are developed that actively avoid collisions and account for disturbance profiles with unknown distributions via distributionally robust checks. Throughout, examples are provided to clarify concepts, simulations and experiments are performed to validate theoretical results, and computer code is made available to promote reproducibility and future discoveries.

Available in PDF, EPUB and Kindle. Book excerpt: An Introduction to Data-Driven Control Systems An introduction to the emerging dominant paradigm in control design Model-based approaches to control systems design have long dominated the control systems design methodologies. However, most models require substantial prior or assumed information regarding the plant’s structure and internal dynamics. The data-driven paradigm in control systems design, which has proliferated rapidly in recent decades, requires only observed input-output data from plants, making it more flexible and broadly applicable. An Introduction to Data-Driven Control Systems provides a foundational overview of data-driven control systems methodologies. It presents key concepts and theories in an accessible way, without the need for the complex mathematics typically associated with technical publications in the field, and raises the important issues involved in applying these approaches. The result is a highly readable introduction to what promises to become the dominant control systems design paradigm. Readers will also find: An overview of philosophical-historical issues accompanying the emergence of data-driven control systems Design analysis of several conventional data-driven control systems design methodologies Algorithms and simulation results, with numerous examples, to facilitate the implementation of methods An Introduction to Data-Driven Control Systems is ideal for students and researchers in control theory or any other research area related to plant design and production.

Available in PDF, EPUB and Kindle. Book excerpt: The Handbook of Dynamic Data Driven Applications Systems establishes an authoritative reference of DDDAS, pioneered by Dr. Darema and the co-authors for researchers and practitioners developing DDDAS technologies. Beginning with general concepts and history of the paradigm, the text provides 32 chapters by leading experts in ten application areas to enable an accurate understanding, analysis, and control of complex systems; be they natural, engineered, or societal: The authors explain how DDDAS unifies the computational and instrumentation aspects of an application system, extends the notion of Smart Computing to span from the high-end to the real-time data acquisition and control, and manages Big Data exploitation with high-dimensional model coordination. The Dynamically Data Driven Applications Systems (DDDAS) paradigm inspired research regarding the prediction of severe storms. Specifically, the DDDAS concept allows atmospheric observing systems, computer forecast models, and cyberinfrastructure to dynamically configure themselves in optimal ways in direct response to current or anticipated weather conditions. In so doing, all resources are used in an optimal manner to maximize the quality and timeliness of information they provide. Kelvin Droegemeier, Regents’ Professor of Meteorology at the University of Oklahoma; former Director of the White House Office of Science and Technology Policy We may well be entering the golden age of data science, as society in general has come to appreciate the possibilities for organizational strategies that harness massive streams of data. The challenges and opportunities are even greater when the data or the underlying system are dynamic - and DDDAS is the time-tested paradigm for realizing this potential.

Book excerpt: Data-driven dynamical systems is a burgeoning field?it connects how measurements of nonlinear dynamical systems and/or complex systems can be used with well-established methods in dynamical systems theory. This is a critically important new direction because the governing equations of many problems under consideration by practitioners in various scientific fields are not typically known. Thus, using data alone to help derive, in an optimal sense, the best dynamical system representation of a given application allows for important new insights. The recently developed dynamic mode decomposition (DMD) is an innovative tool for integrating data with dynamical systems theory. The DMD has deep connections with traditional dynamical systems theory and many recent innovations in compressed sensing and machine learning. Dynamic Mode Decomposition: Data-Driven Modeling of Complex Systems, the first book to address the DMD algorithm, presents a pedagogical and comprehensive approach to all aspects of DMD currently developed or under development; blends theoretical development, example codes, and applications to showcase the theory and its many innovations and uses; highlights the numerous innovations around the DMD algorithm and demonstrates its efficacy using example problems from engineering and the physical and biological sciences; and provides extensive MATLAB code, data for intuitive examples of key methods, and graphical presentations.

This book was released on 2024-07-30 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prosumers, such as energy storage, smart home, and microgrids, are the consumers who also produce and share surplus energy with other users. With capabilities of flexibly managing the generation, storage and consumption of energy in a simultaneous manner, prosumers can help improve the operation efficiency of smart grid. Due to the rapid expansion of prosumer clusters, the planning and operation issues of prosumer energy systems have been increasingly raised. Aspects including energy infrastructure design, energy management, system stability, etc., are urgently required to be addressed while taking full advantage of prosumers' capabilities. However, up to date, the research on prosumers has not drawn sufficient attention. This proposal presents the need to introduce a Research Topic on prosumer energy systems in Frontiers in Energy Research. We believe this Research Topic can promote the research on advanced planning and operation technologies of prosumer energy systems and contribute to the carbon neutrality for a sustainable society.

This book was released on 2024-07-24 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neural network control has been a research hotspot in academic fields due to the strong ability of computation. One of its wildly applied fields is robotics. In recent years, plenty of researchers have devised different types of dynamic neural network (DNN) to address complex control issues in robotics fields in reality. Redundant manipulators are no doubt indispensable devices in industrial production. There are various works on the redundancy resolution of redundant manipulators in performing a given task with the manipulator model information known. However, it becomes knotty for researchers to precisely control redundant manipulators with unknown model to complete a cyclic-motion generation CMG task, to some extent. It is worthwhile to investigate the data-driven scheme and the corresponding novel dynamic neural network (DNN), which exploits learning and control simultaneously. Therefore, it is of great significance to further research the special control features and solve challenging issues to improve control performance from several perspectives, such as accuracy, robustness, and solving speed.
