Real-time Battery State of Charge and parameters estimation through Multi-Rate Moving Horizon Estimator

no code implementations22 Oct 2023 Tushar Desai, Federico Oliva, Riccardo M. G. Ferrari, Daniele Carnevale

For reliable and safe battery operations, accurate and robust State of Charge (SOC) and model parameters estimation are vital.

Separating multiscale Battery dynamics and predicting multi-step ahead voltage simultaneously through a data-driven approach

no code implementations22 Oct 2023 Tushar Desai, Riccardo M. G. Ferrari

The method is based on a sequence-to-sequence learning-based encoder-decoder model, where the encoder infers the slowly varying states as the latent space variables in an unsupervised way, and the decoder provides health-aware multi-step ahead prediction conditioned on slowly varying states from the encoder.

Hybrid Design of Multiplicative Watermarking for Defense Against Malicious Parameter Identification

no code implementations5 Sep 2023 Jiaxuan Zhang, Alexander J. Gallo, Riccardo M. G. Ferrari

Watermarking is a promising active diagnosis technique for detection of highly sophisticated attacks, but is vulnerable to malicious agents that use eavesdropped data to identify and then remove or replicate the watermark.

A Fully Homomorphic Encryption Scheme for Real-Time Safe Control

no code implementations28 Sep 2022 Pieter Stobbe, Twan Keijzer, Riccardo M. G. Ferrari

Fully Homomorphic Encryption (FHE) has made it possible to perform addition and multiplication operations on encrypted data.

Hierarchical Cyber-Attack Detection in Large-Scale Interconnected Systems

no code implementations28 Sep 2022 Twan Keijzer, Alexander J. Gallo, Riccardo M. G. Ferrari

We present a scheme to detect attacks that occur at the local level, with malicious agents capable of affecting the local control.

The Proportional Integral Notch and Coleman Blade Effective Wind Speed Estimators and Their Similarities

no code implementations1 Oct 2021 Yichao Liu, Atindriyo K. Pamososuryo, Sebastiaan P. Mulders, Riccardo M. G. Ferrari, Jan-Willem van Wingerden

This letter introduces two novel BEWS estimator approaches: A Proportional Integral Notch (PIN) estimator based on individual blade load measurements, and a Coleman estimator targeting the estimation in the non-rotating frame.

The Immersion and Invariance Wind Speed Estimator Revisited and New Results

no code implementations15 Apr 2021 Yichao Liu, Atindriyo Kusumo Pamososuryo, Riccardo M. G. Ferrari, Jan-Willem van Wingerden

In this letter, we illustrate that the circle criterion can be used as an alternative method to prove the global convergence of the I\&I estimator.

Detection of Cyber-Attacks in Collaborative Intersection Control

no code implementations8 Apr 2021 Twan Keijzer, Fabian Jarmolowitz, Riccardo M. G. Ferrari

In this paper, we address the safety of Intersection Control algorithms, and design a Sliding-Mode-Observer based solution capable of detecting and estimating false data injection attacks affecting vehicles' communication.

A Topology-Switching Coalitional Control and Observation Scheme with Stability Guarantees

no code implementations8 Apr 2021 Paula Chanfreut, Twan Keijzer, Riccardo M. G. Ferrari, Jose Maria Maestre

In this paper a coalitional control and observation scheme is presented in which the coalitions are changed online by enabling and disabling communication links.
