Continuity of Chen-Fliess series for applications in system identification and machine learning
Dahmen, Rafael; Gray, W. Steven; Schmeding, Alexander (Peer reviewed; Journal article, 2021)Model continuity plays an important role in applications like system identification, adaptive control, and machine learning. This paper provides sufficient conditions under which input-output systems represented by locally ... -

Universal Zero Dynamics : The SISO Case
Gray, W. Steven; Ebrahimi-Fard, Kurusch; Schmeding, Alexander (Peer reviewed; Chapter, 2021)Given a single-input, single-output (SISO) system with a Chen-Fliess series representation whose generating series has a well defined relative degree, it is shown that there is a notion of universal zero dynamics that ... -
Zeroing the Output of Nonlinear Systems Without Relative Degree
Gray, W. Steven; Ebrahimi-Fard, Kurusch; Schmeding, Alexander (Conference object, 2023)The goal of this paper is to establish some facts concerning the problem of zeroing the output of an input-output system that does not have relative degree. The approach taken is to work with systems that have Chen-Fliess ...
