    • 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 ...

    • Continuity of Formal Power Series Products in Nonlinear Control Theory 

      Gray, W. Steven; Palmstrøm, Mathias; Schmeding, Alexander (Peer reviewed; Journal article, 2022)

    • 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 ...
