Robust Optimization Utilizing the Second-order Design Sensitivity Information
This paper presents an effective methodology for robust optimization of electromagnetic devices. To achieve the goal, the method improves the robustness of the objective function by minimizing the second-order sensitivity information, called a gradient index and defined by a function of gradients of performance functions with respect to uncertain variables. The constraint feasibility is also enhanced by adding a gradient index corresponding to the constraint value. The validity of the proposed method is tested with the TEAM Workshop Problem 22.

Abstract

This paper presents an effective methodology for robust optimization of electromagnetic devices. To achieve the goal, the method improves the robustness of the objective function by minimizing the second-order sensitivity information, called a gradient index and defined by a function of gradients of performance functions with respect to uncertain variables. The constraint feasibility is also enhanced by adding a gradient index corresponding to the constraint value. The validity of the proposed method is tested with the TEAM Workshop Problem 22.
