以永磁同步电动机为动力来源矿用电机车控制系统为研究对象，在Matlab/Simulink环境建立了仿真模型，并结合生产实际，在负载、转速变化时对系统的响应进行详细分析，结果表明：输出电流波形接近正弦波，谐波成分小，转矩脉动小，转速稳定，符合工况要求。“,”With the permanent magnet synchronous motor control system for the power source of motor vehicle as the research object, the simulation model is built in the Matlab/Simulink environment.And combined with the actual production, the system was analyzed in detail according to changes of the load and the speed. The results showed that: the output current waveform close to sinusoidal wave, small harmonic components, small torque ripple, speed stability. It meeted the requirements of working conditions.
