摘要
为研究电动汽车飞轮辅助储能系统,对飞轮辅助储能系统中的控制系统进行了运动学控制策略分析,提出了位置环的PID控制策略,并对控制系统进行了硬件和软件的设计,在此基础上搭建了实验平台。基于MATLAB/Simulink进行实验平台的建模,对储能系统的位置估算方法、储能控制方法和释能控制方法进行仿真,通过对仿真结果的分析,研究储能飞轮转速、转矩的对比曲线,得出实际转速和估计转速基本一致。针对实验平台进行了转速控制实验并测试实验平台性能,结果显示PID控制策略可以消除系统2ms的控制延迟现象。该研究为以后飞轮储能装置在飞轮混合动力系统上的应用提供了一定的参考依据。
In order to study the electric vehicle flywheel auxiliary energy storage system, this paper analyzes the kinematics control strategy of the control system in the flywheel auxiliary energy storage system, proposes the PID control strategy of the position loop, and designs the hardware and software of the control system, an experimental platform is built by this basis. Based on MATLAB/Simulink, the experimental platform was modeled, and the position estimation method, energy storage control method and energy release control method of the energy storage system are simulated. The simulation results are analyzed to study the comparison curve of the energy storage flywheel speed and torque. It is found that the actual speed and the estimated speed are basically the same. The speed control experiment was carried out for the experimental platform and the performance of the experimental platform was tested. The results show that the PID control strategy can eliminate the control delay of the system for 2ms. This study provides a reference for the future application of flywheel energy storage devices on flywheel hybrid systems.
