摘　　要：传统测功机台架响应能力和快速切换能力差,缺乏针对性测试方法,难以直接应用于新型电动汽车动力系统测试。因此,基于交流电力测功机的室内台架Labview测试平台,设计了电动汽车测试系统。首先,分析了测试平台的负载模拟原理和基于九点控制的动态切换比例积分微分(PID)控制策略,构建了测试系统硬件平台;然后,利用高级车辆仿真器(ADVISOR)建模仿真,得出工况测试数据;最后,在台架测试平台上进行动力系统测试,完成电动汽车运行时的工况测试。测试结果表明:电力测功机实现了电机两象限快速、稳定的切换,台架系统模拟了电动汽车运行工况,完成了动力系统的性能测试。The response capacity and fast switching ability of the traditional dynamometer platform were poor,which was difficult to directly apply to the new electric vehicle power system testing. Therefore,the indoor bench Labview test platform based on the electric power dynamometer was designed for electric vehicle test system.Firstly,the load simulation principle and dynamic switching proportion integration differentiation( PID)control strategy based on nine point control of the test platform were analyzed,and the hardware platform of the test system was constructed. Then the advanced vehicle simulator( ADVISOR) was used for model and simulation to acquire the test data. Finally,the power system was tested on the test platform to complete the electric vehicle dynamic test.The results show that the power dynamometer realizes the fast and stable switching of the two quadrants of the motor. The bench system simulates the electric vehicle running condition and completes the performance test of the power system.
