Title of the thesis is “Model order reduction for simulation and control of synchronous machines”

Many phenomena in science and every day life can be formulated in mathematical terms. The resulting mathematical formulations are commonly solved using methods known as numerical methods. The finite element method (FEM) is the most popular numerical method in the fields of engineering and physics. Providing a fast and accurate solution to a discretized problem via FEM, is not always an easy task, since the problem may have a high-order system of linear/nonlinear equations, or a large number of design variables. Hence, solving the system of equations can be very costly in terms of both computational time and resources.

This dissertation proposes a reduced model that diminishes the computational complexity and costs of solving numerical simulations significantly. The proposed reduced model is employed in a control system for real-time control of a motor. The high computational efficiency of the reduced model allows direct implementation of the resulting control system in the embedded processor of the drive. The validity of the control system is examined by means of simulations and experiments.
