Study and Optimization of Automotive Suspension Systems Considering Nonlinear Dynamics
Automotive suspension systems play a fundamental role in determining vehicle ride comfort, road holding, and overall handling performance. Modern vehicles operate over a wide range of driving conditions in which suspension components exhibit significant nonlinear behavior due to geometric effects, nonlinear stiffness characteristics, damping properties, and the interaction with road irregularities. The aim of this

Study of the effect of different vehicle models on the lap time optimization
This thesis focuses on the study of the influence of different vehicle dynamic models on lap time optimization, with particular attention to how model fidelity affects optimal control solutions and predicted vehicle performance. Lap time optimization is a central topic in motorsport engineering and high-performance vehicle development, where numerical simulation and optimal control techniques are

Real-time optimal transport of robotic swarms in fluids in 3D domains
Optimally guiding large-scale swarms of drones, underwater vehicles or nanoparticles moving in a fluid is a crucial task in several fields, ranging from medicine to smart delivery. To steer the swarm dynamics avoiding obstacles, controllers must be able to rapidly adapt the optimal action to changes in the external environment, as often happen in applications.

Remote Centre of Motion Compliant Mechanisms as supports for ECRH mirrors
General Introduction on nuclear fusion (reading is strongly advised!) The goal of this activity is to improve the current design of the DTT ECRH mirror flexible supports (see Figure 3). These components are flexible monolithic structures, which allow large rotations of the mirror about its horizontal axis, while being very stiff with respect to all

Optimization of systems with Internal Resonances
MEMS design is usually done following linear vibration theory, however, their real behavior often turns out to be nonlinear. To address this issue, our group developed optimization algorithms to target backbone curves, which are striclty connected to the nonlinearity of the vibration modes. As of now, the backbone computation can target only a single mode.

Adjoint formulation for backbone curve computation at arbitrary order
We have recently proposed a method to tailor the nonlinear response of a structure using Spectral Submanifolds (SSM, or Lyapunov Subcenter Manifolds – LSM) and an optimization procedure1. By defining a set of frequency-amplitude pairs we can fit the backbone curve of the system to these points. The computation of the sensitivities of the LSM,
