摘  要：
为了实现车载电源性能的综合测试,搭建了由直流电动机-飞轮组成的电源测试平台,以此为基础,研究了平台结构对直流调速系统控制精度的影响。建立了测试平台的数学模型,通过实验分析了存在的问题。依据多轴机电传动理论,提出了平台结构的优化方法,建立了优化后平台的数学模型和状态空间方程。分析了无级变速器(CVT)的传动效率,确定了其速比控制约束条件。构建了基于d SPACE的硬件在环测试平台,通过实验分析了平台优化前后直流调速系统的调速效果,实验结果表明,优化后的平台具有优良的调速性能,直流调速系统的跟踪精度显著提高,为开展复合电源性能测试提供了技术支持。

摘  要：
The safety and reliability of electric vehicle depend on the performance of vehicular energy storage system. The test bench composed by DC motor and flywheel was proposed to test the performance of energy storage system. This paper mainly focuses on an improved test bench. The tracking precision of speed control system was affected by the improved test bench. The model and current problems of the test bench were presented. The structure improvement method of the test bench was improved according to the theory of multi-shaft transmission system. The improved test bench was modeled by using state-space equation method. The efficiency and ratio control of continuously variable transmission( CVT) were analyzed. The d SPACE-based hardware-in-the loop( HIL) test bench was built and improved in the lab.Experimental results showed that the tracking precision of speed control system was improved with new test bench. It provides technology support for the performance testing of hybrid energy storage system.
