Identification of oil starvation in hydrodynamic journal bearing using rotor vibration and Extended Kalman Filter
Marcus Vinícius Medeiros Oliveira, André Ricardo Fioravanti, Gregory Bregion Daniel
Oil starvation is a critical fault in hydrodynamic bearings caused by insufficient oil supply flowrate. When late detected, this fault can deteriorate the bearings' performance and…
Autonomous Cooperative Flight Control for Airship Swarms
Pedro G. Artaxo, Auguste Bourgois, Hugo Sardinha +4
This work investigates two approaches for the design of autonomous cooperative flight controllers for airship swarms. The first controller is based on formation flight and the seco…
Estimation of Tire-Road Friction for Road Vehicles: a Time Delay Neural Network Approach
Alexandre M. Ribeiro, Alexandra Moutinho, André R. Fioravanti +1
The performance of vehicle active safety systems is dependent on the friction force arising from the contact of tires and the road surface. Therefore, an adequate knowledge of the…
Hybrid Model-Based and Data-Driven Wind Velocity Estimator for an Autonomous Robotic Airship
Apolo Silva Marton, André Ricardo Fioravanti, José Raul Azinheira +1
In the context of autonomous airships, several works in control and guidance use wind velocity to design a control law. However, in general, this information is not directly measur…
On the Ergodic Control of Ensembles
Andre R. Fioravanti, Jakub Marecek, Robert N. Shorten +2
Across smart-grid and smart-city application domains, there are many problems where an ensemble of agents is to be controlled such that both the aggregate behaviour and individual-…
On Classical Control and Smart Cities
Andre R. Fioravanti, Jakub Marecek, Robert N. Shorten +2
We discuss the applicability of classical control theory to problems in smart grids and smart cities. We use tools from iterated function systems to identify controllers with desir…
