Transmit power policies for stochastic stabilisation of multi-link wireless networked control systems
Alejandro I. Maass, Dragan Nesic, Romain Postoyan +2
Transmit power control is one of the most important issues in wireless networks, where nodes typically operate on limited battery power. Reducing communicating power consumption is…
Policy iteration: for want of recursive feasibility, all is not lost
Mathieu Granzotto, Olivier Lindamulage De Silva, Romain Postoyan +2
This paper investigates recursive feasibility, recursive robust stability and near-optimality properties of policy iteration (PI). For this purpose, we consider deterministic nonli…
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…
Stability analysis of optimal control problems with time-dependent costs
Sifeddine Benahmed, Romain Postoyan, Mathieu Granzotto +3
We present stability conditions for deterministic time-varying nonlinear discrete-time systems whose inputs aim to minimize an infinite-horizon time-dependent cost. Global asymptot…
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…
Robustifying Event-Triggered Control to Measurement Noise
Koen J. A. Scheres, Romain Postoyan, W. P. Maurice H. Heemels
While many event-triggered control strategies are available in the literature, most of them are designed ignoring the presence of measurement noise. As measurement noise is omnipre…
