【摘要】：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。
[Abstract]:Pure electric vehicle power performance test platform is a necessary condition to study the comprehensive performance of electric vehicle. In order to study the power performance of pure electric vehicle, an on-board power performance test scheme composed of DC motor and flywheel is proposed. The DC motor is used to simulate the driving motor of electric vehicle, and the flywheel is used to simulate the load and inertia of electric vehicle. The control model of DC speed regulation system of driving motor is established, and the joint simulation of DC speed regulation system of driving motor is carried out by using Simulink and Psim software. This paper analyzes and compares the DC speed regulation effect of the drive motor under two control strategies: PID control and fuzzy-PID control. A hardware in loop testing platform of on-board power supply performance testing based on dSPACE is established. The reference speed of DC speed regulating system is under simple cycle condition. The simulation results under two control strategies are verified by experiments. The simulation and experimental results show that the fuzzy PID control strategy is superior to the PID control strategy in terms of control accuracy and dynamic performance.
