永磁直线同步电动机优化设计及算法比较

Optimization Design of Permanent Magnet Linear Synchronous Motor and Compare of Algorithm

针对永磁直线同步电动机设计的问题，提出了以单位体积的最大推力为目标函数并建立了相应的数学模型，然 后将遺传算法和随机搜索法分别应用于永磁直线同步电动机优化设计中，优化结果表明，用单位体积最大推力作为永磁直 线同步电动机的优化目标函数是可取的，合理使用两种算法可得到满意的优化结果。

In view of the property of design of the permanent magnet linear synchronous motor （PMLSM）. maximal thrust in unit volume of PMLSM is proposed as object function and corresponding mathematic model is built , then inheritance gene calculation method and random search method are respectively applied in optimal design of PMLSM. The result of optimal design shows that object function according to maximal thrust in unit volume of PMLSM is feasible. Using two arithmetic reasonably can receive satisfactory optimal design result.
