提出了一种径向电磁轴承的优化设计方法。径向轴承的数值优化，使用微分进化-随机直接搜索算法。用二维有限元法求出了磁矢位的非线性解。用麦克斯韦应力张量法计算了该力。对优化前后的轴承参数进行了比较。力，电流增益和位置刚度作为控制电流和转子位移的函数给出。
An optimization of radial active magnetic bearings is presented in the paper. The radial bearing is numerically optimized, using differential evolution-a stochastic direct search algorithm. The nonlinear solution of the magnetic vector potential is determined, using the 2D finite element method. The force is calculated by Maxwell's stress tensor method. The parameters of the optimized and nonoptimized bearing are compared. The force, the current gain, and the position stiffness are given as functions of the control current and rotor displacement.
