Sequential design of experiments techniques for the optimization design of electromagnetic devices

Three sequential design of experiments (uniform, Latin hypercube and central composite designs) techniques are presented to deal with the optimization design problems of electromagnetic devices. These methods can be employed not only as the sampling techniques for the sequential optimization method, but also as a direct sampling optimization method. Thereafter, we use a TEAM Workshop problem to demonstrate the efficiency of the proposed methods. From the experiments and the comparison, we can see that the proposed methods can produce satisfactory solutions, and the compute cost of the total finite element analysis can be remarkably reduced.
