Research Group CADEMA
CADEMA – Computer Aided Design of ElectroMagnetic Apparatuses
The CADEMA research group collects all the Professors belonging to the research sector “Electrical Engineering” of the Department of Energy coordinating their activities. Historically linked to the numerical analysis of electromagnetic fields in components for energy conversion, it has developed several themes of methodological research in the electrical engineering topics.

Research Activities The research group, active within the Energy Department of the Politecnico di Torino, is mainly focused on numerical modelling of electromagnetic and electromechanical devices and systems. Beyond computer aided analysis of electromagnetic fields, a research activity on development of optimization algorithms is present. These main lines of research can be expanded to: Development of numerical analysis codes based on the Cell Method: the application of the numerical technique proposed by Tonti http://www.dica.units.it/perspage/tonti, has produced a family of research codes for the solution of different electromagnetic field and multiphysics conditions. A Matlab based tool for testing numerical formulations has been developed and is used for educational and research purposes. Modelling of magnetic materials: simulation of the behaviour of ferromagnetic materials with main attention to their nonlinear and hysteretic characteristics is carried out. Theoretical and experimental activity on hysteresis modelling is performed together with the implementation of material models inside numerical analysis tools for the computation of industrial devices magnetic fields; Development of micro-magnetic analysis codes: starting from the experience gained in the computation of magnetic field, a research line on dynamic simulation of microscopic behaviour of ferromagnetic materials has been started. Time integration of Landau-Lifshitz-Gilbert equation is interfaced with a hybrid magneto-static Cell Method based code and with thermal field; Analysis and design of industrial devices: both research and commercial codes are used to study and design electromagnetic apparatuses. Area of applications are: electrical machines and actuators, electromagnetic induction devices, shielding systems and industrial electromagnetic compatibility; Theoretical and experimental activity on energy harvesting: electromechanical energy harvesting for different distributed applications is currently studied and prototyped. The activity has led to the publication of two patents; Development of optimization algorithms: scalar and multi-objective optimization algorithms are studied with particular attention devoted to Artificial Immune System (AIS) algorithms. An innovative version of multi-objective AIS has been developed and tested on academic and industrial problems; Application of optimization procedures to energy management and network systems: complex energy nodes with more than one power source present (cogeneration systems, energy micro-grids) require a particular attention to the management of power production in a dynamic prices and costs scenario. Optimal management procedures have been developed both based on classical (Mixed Integer Linear Programming) approach and on more innovative multi-objective stochastic algorithms. |
