When is cumulative dose response monotonic? Analysis of incoherent feedforward motifs
Moh Kamalul Wafi, Arthur C. B. de Oliveira, Eduardo D. Sontag
We study the monotonicity of the cumulative dose response (cDR) for a class of incoherent feedforward motifs (IFFM) systems with linear intermediate dynamics and nonlinear output d…
Boundedness of solutions in feedback systems with antithetic controllers
Moh Kamalul Wafi, Arthur C. B. de Oliveira, Eduardo D. Sontag
Antithetic feedback controllers have become a key experimental and theoretical tool in synthetic biology. Introduced by Khammash and collaborators about 10 years ago, they are empl…
Safe-by-Design: Approximate Nonlinear Model Predictive Control with Real Time Feasibility
Jan Olucak, Arthur Castello B. de Oliveira, Torbjørn Cunis
This paper proposes a computationally lightweight, continuous-time receding-horizon nonlinear model predictive control (MPC) approach with infinitesimal prediction horizon. Unlike…
Convergence Analysis of Gradient Flow for Overparameterized LQR Formulations
Arthur Castello B. de Oliveira, Milad Siami, Eduardo D. Sontag
Motivated by the growing use of artificial intelligence (AI) tools in control design, this paper analyses the intersection between results from gradient methods for the model-free…
Regularizing Numerical Extremals Along Singular Arcs: A Lie-Theoretic Approach
Arthur Castello Branco de Oliveira, Milad Siami, Eduardo D. Sontag
Numerical ``direct'' approaches to time-optimal control often fail to find solutions that are singular in the sense of the Pontryagin Maximum Principle, performing better when sear…
