On the Solvability of Quasi-Regulator Equations in Non-smooth Output Regulation
Zirui Niu, Daniele Astolfi, Giordano Scarciotti
Motivated by the prevalence of non-smooth, possibly non-periodic signals in real-world applications, the output regulation of linear systems subject to non-smooth non-periodic exog…
Approximate Simulation-based Hierarchical Control of Nonlinear Systems
Zirui Niu, Antoine Girard, Giordano Scarciotti
Controlling complex dynamical systems to satisfy sophisticated specifications remains a significant challenge in modern engineering. A promising approach to this problem is the app…
Interconnection-based Model Reduction for Linear Hybrid Systems
Zirui Niu, Giordano Scarciotti, Alessandro Astolfi
In this paper, we address the model reduction problem for linear hybrid systems via the interconnection-based technique called moment matching. We consider two classical interconne…
Bridging Abstraction-Based Hierarchical Control and Moment Matching: A Conceptual Unification
Zirui Niu, Mohammad Fahim Shakib, Giordano Scarciotti
In this paper, we establish a relation between approximate-simulation-based hierarchical control (ASHC) and moment matching techniques, and build a conceptual bridge between these…
Output Regulation of Linear Systems with Non-periodic Non-smooth Exogenous Signals
Zirui Niu, Daniele Astolfi, Giordano Scarciotti
We address the output regulation problem of linear systems with non-smooth and non-periodic exogenous signals. Specifically, we first formulate and solve the full-information probl…
