Oscillations in Mixed-Feedback Systems
Amritam Das, Thomas Chaffey, Rodolphe Sepulchre
A new method is presented for the analysis of limit cycle oscillations in mixed-feedback systems. The calculation of the limit cycle is reformulated as the zero finding of a mixed-…

Scaled relative graphs for system analysis
Thomas Chaffey, Fulvio Forni, Rodolphe Sepulchre
Scaled relative graphs were recently introduced to analyze the convergence of optimization algorithms using two dimensional Euclidean geometry. In this paper, we connect scaled rel…

Monotone RLC Circuits
Thomas Chaffey, Rodolphe Sepulchre
The circuit-theoretic origins of maximal monotonicity are revisited using modern optimization algorithms for maximal monotone operators. We present an algorithm for computing the p…
