Application of progressive quadratic response surface method for an oscillation problem optimization

International audience; The paper presents an effective optimization strategy applied in a physical structure optimization of a semiconductor Power MOSFET with expensive constraint computations. In order to deals with inaccuracy due to inevitable numerical errors in the objective function calculation (the power losses of the power MOSFET), the paper proposes to use the Progressive Quadratic Response Surface Method (PQRSM). The paper focuses on three aspects: the inevitable numerical errors in the power losses computation, the PQRSM principle, and finally the comparisons of several optimization methods on this problem.
