Total stability and integral action for discrete-time nonlinear systems
Samuele Zoboli, Daniele Astolfi, Vincent Andrieu
Robustness guarantees are important properties to be looked for during control design. They ensure stability of closed-loop systems in face of uncertainties, unmodeled effects and…
Decentralized event-triggered estimation of nonlinear systems
E. Petri, R. Postoyan, D. Astolfi +2
We investigate the scenario where a perturbed nonlinear system transmits its output measurements to a remote observer via a packet-based communication network. The sensors are grou…
Towards improving the estimation performance of a given nonlinear observer: a multi-observer approach
E. Petri, R. Postoyan, D. Astolfi +2
Various methods are nowadays available to design observers for broad classes of systems. Nevertheless, the question of the tuning of the observer to achieve satisfactory estimation…
Forwarding-Lyapunov design for the stabilization of coupled ODEs and exponentially stable PDEs
Swann Marx, Daniele Astolfi, Vincent Andrieu
This paper is about the stabilization of a cascade system composed by an infinite-dimensional system, that we suppose to be exponentially stable, and an ordinary differential equat…
Event-triggered observer design for linear systems
E. Petri, R. Postoyan, D. Astolfi +2
We present an event-triggered observer design for linear time-invariant systems, where the measured output is sent to the observer only when a triggering condition is satisfied. We…
Nonlinear Robust Periodic Output Regulation of Minimum Phase Systems
Daniele Astolfi, Laurent Praly, Lorenzo Marconi +1
In linear systems theory it's a well known fact that a regulator given by the cascade of an oscillatory dynamics, driven by some regulated variables, and of a stabiliser stabilisin…
