Complex control systems often contain numerous controllers (or control laws) for a given plant, where the controller having authority at any given time depends on the current operating condition of the plant. For example, a plant operating in the nominal condition generally uses one controller, while a plant with a fault uses a different controller. Even in(More)
Distributed event detection using wireless sensor networks has received growing interest in recent years. In such applications, a large number of inexpensive and unreliable sensor nodes are distributed in a geographical region to make firm and accurate local decisions about the presence or absence of specific events based on their sensor readings. However,(More)
power systems, and telecommunication networks present major challenges to control systems designers. Both the military and civilian sectors of our economy are demanding new and highly sophisticated capabilities from these systems that traditional controls technology is not offering. Among these capabilities are the following: • Adaptability/dynamic(More)
Recent advances in software technology have the potential to revolutionize control system design. This paper describes a new software infrastructure for complex control systems, which exploits new and emerging software technologies. It presents an open control platform (OCP) for complex systems, including those that must be reconfigured or customized in(More)
A sensor network consists of a set of battery-powered nodes, which collaborate to perform sensing tasks in a given environment. It may contain one or more base stations to collect sensed data and possibly relay it to a central processing and storage system. These networks are characterized by scarcity of resources, in particular the available energy. We(More)
projects: Software Enabled Control (SEC), SEC Renegade (a follow-on to the SEC project funded to apply SEC technologies to a full-scale rotorcraft), and Heterogeneous Urban Reconnaissance, Surveillance, and Target Acquisition Team (HURT). My deepest thanks are for Professor George J. Vachtsevanos, who advised me through the completion of this work. His(More)
iii ACKNOWLEDGEMENTS Many thoughts went through my mind as I compiled the work of the past four years to write this dissertation. Most of all, thoughts about the people who helped me to achieve this goal. I w ould like to thank my advisor, Dr. Anthony J. Calise, for his guidance and support in this eeort. His door was always open for me, and his knowledge(More)
