Sampling Strategies for Data-Driven Inference of Input-Output System Properties [article]

Anne Romer, Jan Maximilian Montenbruck, Frank Allgöwer
2019 arXiv   pre-print
Due to their relevance in controller design, we consider the problem of determining the L^2-gain, passivity properties and conic relations of an input-output system.  ...  These sampling strategies are based on gradient dynamical systems and saddle point flows to solve the reformulated optimization problems, where the gradients can be evaluated from only input-output data  ...  In this paper, we present these approaches as a more general idea of the following form: Sampling strategy for inference of system properties: 1) Formulate system property as optimization problem 2) Iteratively  ...
