HEV PMSM 驱动测试框架

打开模型

此示例展示了一个适用于典型混合动力车辆的永磁同步电机 (PMSM) 驱动测试框架。该测试框架可用于确定在给定转速和转矩下运行时的总驱动损耗。然后，Simscape™ Electrical™ Motor & Drive (System Level) 模块可以使用此测试框架提供的损耗信息表来对完整的驱动周期进行快速仿真，同时仍然准确预测整体系统效率。

来自示波器和 Simscape 记录的仿真结果

下面的第一张图显示来自频谱分析仪的结果。第二张图显示测得转子转速和指令转子转速。此外，还绘制了绕组电流，这解释了电机转速中的高频波纹。

下表显示了 PMSMDrive 模型中各个组件的耗散功率。这些总损耗数是使用仿真结果中记录的 Simscape 变量和损耗计算实用工具 ee_getPowerLossSummary 计算得出的。表中列出了负载端的总输出功率以及各组件的损耗。

Efficiency = 86.0071% when speed = 1400rpm and torque = 200Nm
Losses in watts by component are as follows:
