摘　　要：针对新一代轨道交通列车模块化、小型化、轻量化带来的电磁噪声问题,提出了一种基于宽频段随机载波频率的控制策略,该方法可以动态调节电机磁场强度大小,并且可以宽范围调节载波频率,减小电机的电磁噪声。进行MATLAB仿真及线路运行试验,对比分析谐波含量和噪声情况,验证了所提算法的合理性和可行性,为轨道交通列车降噪设计提供了新思路。In view of the electromagnetic noise problem caused by the modularization,miniaturization and lightweighting of the new generation of rail transit trains,a control strategy based on wide-band random carrier frequency was presented.This method can dynamically adjust the magnetic field intensity and the carrier frequency in a wide range,reducing the electromagnetic noise of motor.MATLAB simulation tests and on-track operational tests were conducted,a comparative analysis of harmonic content and noise levels was complemented,the rationality and feasibility of the proposed algorithm were verified,offering a novel approach for noise reduction design in rail transit vehicles.
