“Mobile Actuator and Sensor Networks (MAS-nets) for Cyber-Physical Systems”
Computational thinking and integration of computation around physical dynamic systems form the cyber-physical systems (CPSs) where sensing, decision, actuation, computation, networking and physical processes are mixed. It’s predicted that CPSs will “transform how we interact with the physical world just like the Internet transformed how we interact with one another” and that CPSs “will be everywhere, used by everyone, for everything.”  CPSs will be mostly infinite-dimensional spatial-temporal complex dynamic systems. Therefore when we consider the measurement and control of distributed parameter systems, we need first to consider the spatial domain of interest and then to consider the actuator/sensor configurations. We should consider if 1) the sensor/actuators are collocated or noncollocated; 2) sensor/actuators are point, filament, regional, whole domain or boundary; 3) sensor/actuators are movable or static; and 4) sensor/actuators are communicating to their neighbors or not. So there are 2x5x5x4x4 = 800 possibilities. There are obviously rich and exciting research questions with today’s technology. This lecture will summarize research efforts on mobile actuator and sensor networks (MAS-nets) at CSOIS (the Center for Self-Organizing and Intelligent Systems) since 2002. Movie clips will be shown from some preliminary results of mobile actuator and sensor networks for cyber-physical systems.
YangQuan Chen is an associate professor of electrical engineering at Utah State University. He earned his Ph.D. from Nanyang Technological University in Singapore in 1998. His current areas of research interest include distributed measurement and distributed control of distributed parameter systems using mobile actuator and sensor networks, smart mechatronics and controls (intelligent, optimal, robust, nonlinear and adaptive), applied fractional calculus, UAV cooperative control for remote sensing, and real-time water management and irrigation control. He holds 13 granted and two pending U.S. patents. He is an author of two research monographs, six textbooks and over 100 refereed journal papers and book chapters. His latest research monograph is “Optimal Observation for Cyber-Physical Systems: A Fisher-information-matrix-based Approach.” He was and will be the program chair for the ASME/IEEE International Conference on MESA (Mechatronics and Embedded Systems and Applications) 2007 and 2009. He has been an associate editor for the IEEE CSS Conference Editorial Board since 2002. He is a senior member of IEEE and a member of ASME, AUVSI, the Academy of Model Aeronautics, the American Water Resources Association and the American Society of Engineering Educators.
