1车载电源性能测试平台驱动电机调速系统控制策略研究显示文摘纯电动汽车电源性能测试平台是研究电动汽车综合性能的必备条件。为研究纯电动汽车电源性能,提出由直流电机-飞轮组成的车载电源性能测试方案,直流电机用来模拟电动汽车驱动电机,飞轮用来模拟电动汽车的负载和惯量。建立了驱动电机直流调速系统的控制模型,运用Simulink和Psim软件对驱动电机的直流调速系统进行联合仿真,分析并比较了PID控制和模糊-PID控制两种控制策略下驱动电机的直流调速效果;建立了基于dSPACE的车载电源性能测试硬件在环测试平台,以简单循环工况为直流调速系统的参考转速,通过实验对两种控制策略下的仿真结果进行了实验验证。仿真和实验结果均表明模糊-PID控制策略在控制精度和动态性能方面优于PID控制策略。李勇 马飞 KAZERANI Mehrdad 2014中国电机工程学报2014,34,21:8
2Numerical study of the semi-circular bend dynamic fracture toughness test using discrete element models显示文摘The semi-circular bend(SCB) dynamic fracture toughness test is simulated using discrete element models. The influence of the frictional boundary condition, constitutive law and specimen thickness on the test measurements is investigated. It is found that friction between loading plates and the rock specimen affects the test results. Therefore, friction must be carefully considered to obtain accurate measurements. The simulation results also show that in contrast to the 2D model in which a rate-dependent cohesive law must be introduced, 3D models with a rate-independent law can produce good results. Furthermore, the study suggests that test measurements are seriously affected by specimen thickness; thus, full 3D modeling is required for simulation of the SCB test.ZHAO GaoFeng KAZERANI Tohid MAN Ke GAO Mz ZHAO Jian 2015Science China(Technological Sciences)2015,58,9:4
3纯电动汽车车载电源性能在环测试平台研究显示文摘为研究纯电动汽车车载电源性能,提出并搭建了由异步电动机和直流电动机组成的在环测试平台.异步电动机用来模拟纯电动汽车的牵引电动机,直流电动机用来模拟汽车行驶时的阻力和惯量,对异步电动机和直流电动机分别实施转速控制和转矩控制.分析了电动汽车行驶工况,给出了简单循环工况下参考转速、转距和功率.设计了异步电动机调速系统转速控制器和电流控制器,建立了异步电动机调速系统的数学模型,提出了基于自适应模糊神经网络控制的异步电动机调速系统.仿真和实验结果表明,基于自适应模糊神经网络控制的调速系统明显优于PID控制的交流调速系统,在环测试平台能够较好跟踪参考转速和参考转距的变化.李勇 Mehrdad Kazerani 马飞 2014北京科技大学学报2014,36,10:3
4车载电源多电动机测试平台耦合分析与解耦控制研究显示文摘为研究纯电动汽车车载电源性能在环测试,提出了由异步电动机-直流电动机组成的测试平台,是集机、电、磁于一体的复杂机电耦合系统。首先对该测试平台进行了机电耦合分析,建立了其机电耦合模型。根据α阶积分逆系统原理构建了伪线性系统,实现了对该复杂机电耦合系统的线性化。在此基础上,将自适应模糊神经网络与逆系统结合,构造出自适应模糊神经网络逆系统对原系统进行解耦控制。仿真和实验结果表明:自适应模糊神经网络逆系统控制取得了较好的解耦效果;异步电动机的反馈转速和直流电动机的反馈转矩均较好地跟踪了参考转速和参考转矩。此外,通过该测试平台可得到在整个循环工况中与异步电动机相连的电池电压、电流以及功率的变化曲线,为复合电源的在环测试提供了理论依据。李勇 马飞 Kazerani Mehrdad 2014农业机械学报2014,45,7:2
