High-Speed,High-Power Motor Design for a Four-Legged Robot Actuator Optimized using the Weighted Sum and Response Surface Methods

In this paper,a design is presented for a high-speed,high-power motor for a four-legged robot actuator that was optimized using the weighted sum method(WSM)based on the Taguchi method,and the response surface method(RSM).First,output torque,torque constant,torque ripple,and efficiency were selected as objective functions for the optimized design.The sampling method was implemented to use a mixed orthogonal array and the single response characteristics of each objective function were compared using the Taguchi method.Moreover,to consider the multi-response characteristic of the objective functions,WSM was applied.Second,the 2D finite element analysis result of the RSM was compared with that using the WSM.Finally,an experiment was carried out on the manufactured motor and the optimized model is presented here.

用于电流馈电双有源桥式变换器的控制漏感高频变压器的设计优化

用于光伏发电的电流馈电双有源电桥转换器通常可能需要给定的泄漏或额外的电感，以便提供对电流的适当控制。因此，许多研究都集中在高频变压器的漏感控制上，以集成一个额外的电感器。本文提出了一种非对称绕组配置，以获得高频变压器的受控漏电感，以提高电流馈电双有源桥式变换器的效率。为了精确分析，该设计使用了与高频开关电路相连的变压器的耦合电磁分析模型。通过利用设计分析模型，给出了高效率的设计优化步骤，并通过实验结果验证。
