State estimation of an electrochemical lithium-ion battery model: improved observer performance by hybrid redesign

Autor: Petri, E., Reynaudo, T., Postoyan, R., Astolfi, D., Nesic, D., Rael, S.

Effective management and just-in-time maintenance of lithium-ion batteries require the knowledge of unmeasured (internal) variables that need to be estimated. Observers are thus designed for this purpose using a mathematical model of the battery inte

Hybrid multi-observer for improving estimation performance

Autor: Petri, E., Postoyan, R., Astolfi, D., Nesic, D., Andrieu, V.

Various methods are nowadays available to design observers for broad classes of systems, where the primary focus is on establishing the convergence of the estimated states. Nevertheless, the question of the tuning of the observer to achieve satisfact

Decentralized event-triggered estimation of nonlinear systems

Autor: Petri, E., Postoyan, R., Astolfi, D., Nešić, D., Heemels, W. P. M. H.

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 grouped into N nodes and each of these nodes decides when its measured dat

Towards improving the estimation performance of a given nonlinear observer: a multi-observer approach

Autor: Petri, E., Postoyan, R., Astolfi, D., Nešić, D., Andrieu, V.

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 performance remains largely open. This paper presents a general super

Event-triggered observer design for linear systems

Autor: Petri, E., Postoyan, R., Astolfi, D., Nešić, D., Heemels, W. P. M. H.

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 proceed by emulation and we first construct a continuous-time Luenber
