Electromechanical motion systems for naval and submarine applications


Marine propulsion and handling systems, both for surface ships and submarines, have undergone a profound transformation in recent decades, relating to motion transmission and control. This change, often defined as a real generational leap, leads to a technological transformation to move from predominantly hydraulic mechanisms to electrical implementations.
This evolution has been fuelled by the great technological advances that have characterized the field of servo motors and their control, as well as by the worldwide demand to use “green” energy. Replacing hydraulic systems with electric ones has many advantages, such as the elimination of the hydraulic power station and the transmission oil, improved efficiency, and a finer motion control. On the other side, challenges emerge from lower power density, electromagnetic interference, and larger magnetic signature.  This research project focuses on the study of a new-generation of electromechanical actuation systems in the perspective of performance maximization and reduced environmental impact.

Project Goals

The specific aims of the project are:

  • to analyse, design and optimize servo mechanisms and electrical drives according to stringent specifications concerning dynamic loads, as well as acoustic and magnetic signature;
  • to design and optimize motion laws and actuator control, in order to maximize performance.

In collaboration with: Calzoni – L3Harris
