摘　　要：在分析现有禁忌算法(Tabu)基础上,该文提出了一种改进的连续变量全局优化Tabu算法。以永磁直线同步电动机减小推力波动为优化设计目标,把改进的禁忌搜索算法与电磁场逆问题分析法相结合,对一台永磁直线同步电动机实施了优化设计。优化设计结果表明,磁阻力得以大大降低,实现了PMLSM动子铁心长度、永磁体宽度的优化设计。An improved Tabu search algorithm for the optimization of functions with continuous variables was proposed in this paper based on the thorough study of the Tabu search method so far used.A permanent magnet linear synchronous motor（PMLSM） was successfully optimized thanks to the successful application of an improved Tabu search algorithm combined with inverse problems of electromagnetic field with the thrust fluctuations reduction of the PMLSM as the optimal objective.The numerical results obtained in this study reveals that detent force is greatly reduced and the mover core length,permanent magnet width of the PMLSM are optimized.
