Provide an efficient robust model in frequency and time domains, optimized for distinctive detection of metals by electromagnetic induction technology with features like material, shape and size discrimination. Distinctive detection is the main scientific contribution of this work. The challenge against superposition of signals and interferences makes it very difficult for discriminating the above features at low frequency (less than MHz). Machine learning algorithms were applied in regression of physically parametrized time series of electric signals (pulsed and harmonic) induced by magnetic signals. The training and optimization were based on experimental data. Prediction resolution was improved enormously in spite the reduction of complexity. This work has been protected by two patents at the end. Feature selection, feature reduction, nonlinear optimizations, robust predictions, and smart discrimination were all performed with various mathematical tools and algorithms. Validations of many scenarios in tests were self-defined and executed.

Research topics:

 

    • optimization of electromagnetic eddy current drive

Global optimization using particle swarm and genetic algorithms for constrained multi-objective optimization. (MATLAB, self-written tools)

    • machine learning: supervised, unsupervised, reinforced

Machine learning methods for optimization purposes of electromagnetic drives. The training of data (simulation and experimental) lead to fast accurate models that can be used for optimization purposes or active control. Deep learning is used for time series regression. Artificial Intelligence of drives is implemented on few applications as well. (Python, MATLAB, WEKA)

    • batteries

Integrated in the research and development team of Lithium batteries from research to experimental validations of single cells to fully industrialized batteries. The work involved implementing of a virtual model on the cell and pack level to be used in the testing and development teams. The model is successfully validated and used in battery development for power tools. (ANSYS, MATLAB)

    • electromagnetic drives R&D

Integrated in the research and development team of battery driven tools for direct fastening application. The work involved a creation of an accurate virtual tool for an eddy current electromagnetic drive that is successfully validated and being used as a reference in drive development for direct fastening tools. The research involved coupling of electro-magnetic-thermal-structural fields with an integration of global optimization model subjected to equality and non-equality constraint. (ANSYS, MATLAB)

    • motors and actuators

Creation and implementation of a transient electromagnetic Finite Element Method preserving eddy currents and changing reluctance. The model is validated with functional demonstrator. (ANSYS, MATLAB)

    • induction heating, induction hardening, underground detection

Creation and implementation of a transient finite element model. It is experimentally validated (voltage and current measurements) for medium frequency electromagnetic fields coupled to heat transfer with a two-way coupling.

    • motors and actuators

Quasi-static electromagnetic simulation of linear motor concepts (ANSYS, Simulink). Simplified mode for fast comparison of concepts

    • motors and actuators

Improvement of motor cooling using Computational Fluid Dynamics with conjugate heat transfer (ANSYS CFX)

 

Miscellaneous Tasks:

 

    • High performance computing (HPC), migration and implementation of commercial software from a single node UNIX server to a Linux cluster. Supporting the optimization of parallel computing
    • CFD simulation of different blade shapes of a mixer of two fluids (ANSYS CFX)
    • Explicit dynamics simulation of impact mechanisms (LSDYNA)
