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…
Dynamic allocation function design in the presence of magnitude saturating inputs
Thiago Alves Lima, Sophie Tarbouriech
This chapter deals with the design of dynamic allocation functions for systems with saturating actuators. The goal of the allocator consists in redistributing the desired control e…
