Background

Dr Luca Zanotti Fragonara is Lecturer in the Centre of Autonomous and Cyber-Physical Systems and in the Aerospace Integration Research Centre.

His research is focused on structural health monitoring, machine learning and system identification. He is involved in a series of high-impact research projects ranging from autonomous inspections of aerospace structures to structural health monitoring for increasing the resilience of industrial plants. 

He matured a wide and unique experience working in monitoring problems applied to civil, mechanical, aerospace and space structures. Moreover, his interests in machine learning applied to monitoring allowed him to expand his research activities to other areas, such as perception, tracking and sensor fusion.

He has a solid knowledge in vibration problems, non-linear dynamics problems and in finite element modelling.

Current activities

Lecturer, Cranfield University, Centre for Autonomous and Cyber-Physical Systems, Aerospace Integration Research Centre. I am involved in several project linked to: 

  • autonomous inspections for non-destructive evaluation of aircraft composite materials (http://compinnova.eu/);
  • Multi User Environment for Autonomous Vehicle Innovation (https://www.cranfield.ac.uk/facilities/mueavi);
  • autonomous inspections using drones of metallic panels;
  • artificial intelligence for perception, object detection, classification;
  • validation of AI models (https://humandrive.co.uk/);
  • structural health monitoring for building resilience (https://r.unitn.it/en/dicam/xp-resilience).
I worked on other projects such as:
  • Vibration-based monitoring of CubeSat;
  • Land3U (https://www.esa.int/Education/Drop_Your_Thesis/Meet_the_teams_Land3U);
  • Condition monitoring of foundation piles;

I teach Sensor Fusion, Artificial Intelligence (Supervised and Deep Learning) and Finite Elements in the AVDC, ASE and CSTE MSc at Cranfield.

My wide interests are in Structural Health Monitoring of Civil, Mechanical and Aerospace structures, Non-linear dynamics, Finite Element modeling and statistical signal processing.

I am involved in MSc students’ supervision during their final thesis, in teaching activities, and research project management activities.

In more detail my major areas of expertise concerns: 

  • Finite Element modelling: linear, non-linear and dynamic models.
  • Machine Learning algorithms: gradient-descent, logistic regression for multiclass classification, clustering techniques (K-means), Neural Networks, CNNs, R-CNNs, Support Vector Machine (SVM), Anomaly detection algorithms, Principal Component Analysis (PCA).
  • Numerical methods for Ordinary Differential Equations (ODEs), Volterra series, Associated Linear Equations (ALEs), Differential Algebraic Equations (DAEs).
  • Nonlinear System identification algorithms: Unscented Kalman Filtering, Particle Filters, Time-Frequency Instantaneous Estimators, Sigma-Point Filters (SPF), Neural Networks, and Autoregressive models (e.g. NARMAX).
  • Dynamic Identification techniques and experimental modal analysis: time-domain methods (Stochastic Subspace Identification, Eigen-system Realization Algorithm, Neural Networks, Autoregressive models), frequency-domain methods (Frequency Domain Decomposition) and time-frequency domain method (Time-Frequency Instantaneous Estimators, Short-Time Fourier, Choi-Williams, Wigner-Ville based methods, Chirp Fourier Transform, Bi- and Tri-coherence transform).
  • Nonlinear normal modes and chaos dynamics: shooting methods, arc-length method, pseudo-arc length method.
  • Global sensitivity analysis techniques (Elementary Effect, Diffused partial-derivatives, Variance-based methods) and meta-modelling techniques.
