The numerical optimization of an inductor for traction drive systems-a parametric optimization environment

Optimum design is defined as a design that is feasible and the best solution possible. All design variables are determined simultaneously so as to satisfy a set of constraints and optimize a set of objectives. Here, a parametric preprocessor and a general purpose optimization environment are presented. Both are implemented in MATLAB, providing the graphical interface and controlling external processes. Due to the open architecture of the package, finite element as well as analytical models can be implemented. An optimization task is discussed to outline the general application range of the tools. The optimum design of an inductor used in a traction drive system is described in detail. Special attention is paid to the formulation of the quality function.
