摘　　要：传统电机的弱磁补偿受到复杂特性的影响,容易陷入局部最优解,导致无法达到理想的补偿效果。因此,提出电感参数FPSO辨识下永磁同步电机弱磁补偿控制方法。考虑交叉耦合计算磁链,构建电感参数模型。结合FPSO辨识算法,寻找最优电感参数。引入基于迭代次数与粒子序号的函数,评估不同控制参数组合下弱磁补偿的效果。考虑电流、电压约束条件,实现对弱磁控制和补偿。实验结果表明,该方法在d轴和q轴电流的弱磁控制范围内,与预设范围最大误差为0.01A,具有高效补偿控制效果。The weak magnetic compensation of traditional motors is affected by complex characteristics and is prone to getting stuck in local optimal solutions,resulting in the inability to achieve the desired compensation effect.Therefore,a weak magnetic compensation control method for permanent magnet synchronous motors is proposed under the identification of inductance parameter FPSO.Consider cross coupling calculation of magnetic flux and construct an inductance parameter model.Combining FPSO identification algorithm to find the optimal inductance parameters.Introduce a function based on iteration number and particle number to evaluate the effectiveness of weak magnetic compensation under different control parameter combinations.Consider current and voltage constraints to achieve weak magnetic control and compensation.The experimental results show that the method has a maximum error of 0.01 A compared to the preset range within the weak magnetic control range of d-axis and q-axis currents,and has an efficient compensation control effect.
