A Theory of Nonlinear Negative Imaginary Systems
… establish the stability robustness of a positive feedback interconnection of negative imaginary systems in the linear case under a set of theoretical assumptions. Then, these assumptions will be adapted in the nonlinear setup to establish the stability robustness analysis of a positive feedback …

Convex optimization methods for model reduction
… as an L2 gain upper bounding problem of some feedback interconnection, to which the small gain theorem can be applied. A numerical procedure based on integral quadratic constraint analysis and a theoretical statement based on L2 gain analysis are given to provide the solution to the error …

Passivity, no-regret, and performance in online learning and games
… a learning dynamic model is modeled as a cascade interconnection between a diagonal LTI map $G(s)=g(s)I_n$ and the softmax nonlinearity, linking the frequency response $g(j\omega)$ (gain and phase) directly to asymptotic performance. We introduce payoff-based higher-order variants of replicator …

Control and stability of autonomous inverter-based microgrids
… that microgrids can be described as the negative feedback interconnection of the two subsystems. Using the passivity framework, local conditions are imposed for stability at each inverter, the passivity properties of various existing control strategies for microgrids are assessed numerically, and …

Advances in the stochastic and deterministic analysis of multistable biochemical networks
This dissertation is concerned with the potential multistability of protein concentrations in the cell that can arise in biochemical networks. That is, situations where one, or a family of, proteins may sit at one of two or more different steady state concentrations in otherwise identical cells, …
