【摘要】 飞轮电池作为一种新概念蓄电池,具有高密度储能、大功率输出、充放电时间快、无污染、使用寿命又长等优点,在能源缺乏、环境污染越来越严重的今天,研究并开发出飞轮电池是有重要意义的。本论文在查阅了许多国内外相关研究的基础上,以电动车辆和不间断电源(UPS)为应用背景,进行了飞轮电池充放电控制系统的硬件电路和软件的设计。选择TMS320F2812作为系统控制器,通过应用矢量控制和直流升降压斩波技术,采用电流、转速双闭环控制,结合多种保护措施和降低功耗方法,使得该系统具有工作安全可靠、功耗低等优点。在选用永磁同步电机作为飞轮电机的基础上,利用MATLAB建立了永磁同步电机控制系统的仿真模型,仿真结果验证了模型的可行性。针对永磁同步电机具有非线性、强耦合性和时变性,以及系统运行时会受到不同程度的干扰,常规PID控制策略很难满足高性能的控制要求,本文设计了一种基于模糊控制的参数自适应PID控制器,将其作为永磁同步电机电流和速度双闭环矢量控制系统的转速调节器,仿真实验结果证明了系统具有较好的动态性能和鲁棒性。更多还原

【Abstract】 As a new concept of flywheel battery,it has a high density, high power output, rapid charge and discharge time, no pollution, nature and long life advantages, with energy shortages, worsening pollution increasingly today, the research and development of the flywheel battery is very important.Under reading a lot of domestic and foreign study about flywheel battery, this paper for the purpose of the application of the flywheel battery on the electric vehicle and uninterruptible power supply(UPS).I complete the design of hardware and software about flywheel battery charge and discharge control system.This system Chose the TMS320F2812 as the system controller, and the system is on the safe side and higher efficiency, because of using the field oriented controlled modem technology and the Boost-Buck converter of DC, the closed loop control of current and speed,and combining with many ways of safeguard and reducing power wasting.The paper chose permanent magnet synchronous motor(PMSM)as the flywheel motor according to the character of the fly wheel storage system.The simulation model of PMSM control system is built in MATLAB.The feasibility of the simulation model is proved.Then,because the flywheel motor has non-linearity, close coupling and time-variance and the system also receives disturbance in varying degrees,it is difficult for traditional PID controller to achieve satisfactory control effect of higher precision. So the paper research into the intelligent control to flywheel store system. The theory of fuzzy logic control is elaborated detailedly. The fuzzy self-adjusting PID controller is designed and used as the speed controller of current and speed double loops PMSM vector control system. The simulation results prove that the system has good dynamic performance and robustness.更多还原
