Voice coil actuator is a new kind of direct drive motor. It has many good performances, such as high acceleration and fast response. We present an improved sequential optimization method (SOM) and dimension reduction optimization method to design optimization a cylindrical voice coil actuator in this work. In the implementation, design of experiments (DOE) technique and Kriging approximate model are employed to improve the optimization efficiency. From the discussion, we can see that the proposed methods are very efficient. And computation cost of finite element analysis can be reduced remarkably (more than 2/3 of the cost has been saved) by the proposed methods.Keywords-design of experimants, finite element analysis, Kriging model, sequential optimization method, voice coil actuator.

This paper concerns the comparison of three linear reluctance actuators and four voice coil actuators for high-precision applications. The short-stroke actuators with reasonably low variation of the force are optimized on actuator mass and power dissipation. For actuators with a significantly high force variation, the configuration is modified with the objective to improve the actuator properties for high-precision applications. Finally, the comparison is made on performance regarding, force, mass, losses and stiffness.

“…SM replaces the optimization of an expensive or “fine” model by means of the iterative optimization and updating of so‐called “coarse” model, which is less accurate but cheaper to evaluate. Recently, a number of new SM developments [11–18] and application studies [19–29] have been reported, also in conjunction with artificial neural networks [30–37], and tuning methodologies [38–40].…”

Space mapping (SM) is one of the most efficient simulation-driven design technologies used in microwave engineering to date. It includes so-called output SM that ensures exact matching between the EM-evaluated microwave structure under consideration (fine model) and its surrogate at the current design. The standard, single-point output SM exploits the fine model data at a single design and is not able to align the models' sensitivity. Here, a multipoint response correction is proposed that generalizes the concept of output SM. By using a design-variable-dependent correction term and exploiting all available fine model information, the proposed technique provides exact match between the surrogate and the fine model at several designs. This retains the benefits of output SM but also enhances sensitivity matching between the two models, which results in improved performance of the SM optimization process. The efficiency of the propose approach is demonstrated using several microwave design problems.
