Abstract

In order to weaken the torque ripple caused by cogs torque and increase the output torque of permanent magnet synchronous motor, this paper proposes a multi-objective optimization method of permanent magnet synchronous motor based on Improved Multi-Objective Salp Swarm Optimization Algorithm (IMOSSA) and Spearman correlation analysis. Firstly, the improved strategy of Multi-Objective Salp Swarm Algorithm (MOSSA) was proposed, and the effectiveness of the improved algorithm was further verified by the performance test of the algorithm. Then, the motor simulation model was established, and the high correlation parameters were filtered out by Spearman correlation analysis. The response surface model was established by Response Surface Method (RSM), and the regression equation was given. The IMOSSA was used for iterative optimization. Through optimization, the experimental results show that under the premise of meeting the efficiency design requirements, the average output torque of the motor is increased by 21.35%, the torque ripple and cogging torque are reduced by 45.04% and 39.17% respectively, which verifies the effectiveness and feasibility of the proposed method.

基于改进 Salp Swarm 算法和斯皮尔曼相关性的永磁电机多目标优化技术

为了减弱齿轮转矩引起的转矩纹波，提高永磁同步电机的输出转矩，本文提出了一种基于改进的多目标萨尔普群优化算法（IMOSSA）和斯皮尔曼相关分析的永磁同步电机多目标优化方法。首先，提出了多目标萨尔普群算法（MOSSA）的改进策略，并通过算法性能测试进一步验证了改进算法的有效性。然后，建立了电机仿真模型，并通过斯皮尔曼相关分析筛选出高相关参数。采用响应面法（RSM）建立了响应面模型，并给出了回归方程。采用 IMOSSA 进行迭代优化。通过优化，实验结果表明，在满足效率设计要求的前提下，电机的平均输出转矩提高了 21.35%，转矩纹波和齿槽转矩分别降低了 45.04% 和 39.17%，验证了所提方法的有效性和可行性。
