Abstract

The approach of the paper regards analysis of a light electric vehicle used for urban mobility via real-time simulation with experimental validation. Using a dedicated software, National Instruments VeriStand, the authors prove the possibility of performing vehicle testing for a period of actual mobility time recorded inside the urban scenario. Such long-time simulations are extremely time consuming or impossible to perform using computer-based simulators. One solution is to decrease the model complexity in order to perform these simulations, however the computation time still reaches periods beyond the actual analyzed one. Using VeriStand, the model complexity is kept at its maximum, hence the accuracy and the performances are not diminished. The required computation time is the actual mobility time. Hence, the same time can be applied for an actual test-bench, proving via comparative analysis the quality of the results and the accuracy of the model under test. The considered application is an electric scooter, equipped with a 300W permanent magnet synchronous machine (PMSM), supplied via an inverter from a source of 36 VDC. The model of the PMSM is a flux-linkage one designed in Matlab Simulink and exported into VeriStand running on a NI-PXIe 8135 Embedded Controller. The entire study is validated with experimental measurements performed with the actual machine under study.
利用VeriStand软件构建城市轻型电动车实时模型
本文对一种用于城市交通的轻型电动汽车进行了实时仿真分析,并进行了实验验证。使用专用软件,国家仪器VeriStand,作者证明了在城市场景中记录一段实际移动时间进行车辆测试的可能性。这种长时间的模拟非常耗时,或者不可能使用基于计算机的模拟器来执行。一种解决方案是降低模型复杂度以进行这些模拟,但是计算时间仍然超出实际分析的时间。使用VeriStand,模型复杂性保持在最大,因此精度和性能不降低。所需的计算时间为实际移动时间。因此,同样的时间可以应用于实际的试验台,通过对比分析来证明结果的质量和被测模型的准确性。考虑的应用是一辆电动滑板车,配备一台300W的永磁同步电机(PMSM),通过逆变器从36 VDC电源供电。永磁同步电机的模型是在Matlab Simulink中设计的磁链模型,并在NI-PXIe 8135嵌入式控制器上导出到VeriStand。整个研究都是通过实验测量来验证的,实验测量是用实际的机器进行的。
