Robustness Metrics for Structured Control Systems
Abstract
The overall objective of this fundamental research project is to develop a novel stabilityand performance robustness theory and associated computational tools which exploit themathematical structure of systems that are widespread in Navy control studies and beyond. Theproject will seek answers to key questions such as: Is a robustness theory which exploits thespecific mathematical structure of systems of interest, e.g. second order systems, and theirassociated uncertainties less conservative than existing theory, developed for first order systems?To what extent the conservativeness can be reduced and what is the price paid, e.g. is thecomputational complexity significant? Analytical investigations will be first pursued to addressthese questions and build novel robustness theories centered on the specific mathematicalstructure of interest. The associated theoretical results will be used to develop algorithms forpractical implementation. The algorithms will be tested on benchmark examples such as marinevehicles, structures, and air vehicles that are relevant to the Navy. Validation studies will becarried out to assess the utility of the theory and computational tools, computational complexityand for quantification of improvement over the current state of the art. This research willadvance fundamental understanding in the way we characterize and measure stability andperformance of general automated control systems, thus having broad applicability. The researchwill result in future Navy systems that can perform larger sets of missions, with largeroperational envelopes, at maintenance and implementation costs that will likely be lower than thecurrent ones.
