Pattern preservation in finite to infinite-horizon optimal control problems for dissipative systems
Matteo Della Rossa, Thiago Alves Lima, Lorenzo Freddi
This paper focuses on infinite-horizon optimal control problems for dissipative systems and the relations to their finite-horizon formulations. We show that, for a large class of p…
Feedback stabilization of switched systems under arbitrary switching: A convex characterization
Thiago Alves Lima, Matteo Della Rossa, Antoine Girard
In this paper, we study stabilizability of discrete-time switched linear systems where the switching signal is considered as an arbitrary external input (and not a control variable…
Feedback Stabilization of Switched Systems: Memory is not needed
Thiago Alves Lima, Matteo Della Rossa, Antoine Girard
A long-standing assumption in the literature on switched linear systems is that static, homogeneous of degree one feedbacks form the most general class of controllers necessary and…
Exploiting Over-Approximation Errors as Preview Information for Nonlinear Control
Antoine Aspeel, Antoine Girard, Thiago Alves Lima
We study the control of nonlinear constrained systems via over-approximations. Our key observation is that the over-approximation error, rather than being an unknown disturbance, c…
Fixed-Time and Arbitrarily Fast Exponential Stabilization of Discrete-Time Switched Linear Systems
Picchiotti Flavio, Thiago Alves Lima, Girard Antoine
In this paper we first study the fixed-time stabilizability of discrete-time switched linear control systems. Using a geometric approach, we derive conditions under which such syst…
