摘　　要：[目的]线性涡流制动装置是磁浮列车的关键技术之一,但该技术目前仍不够成熟。对涡流制动技术进行研究,具有非常重要的理论意义和应用价值。[方法]建立了中低速磁浮列车线性涡流制动装置的模型,推导得到总涡流制动力F的计算式。为验证所设计涡流制动装置的减速效能,研制了涡流制动实物装置,并进行了台架试验。建立了电磁涡流制动力矩控制系统模型,分别基于开环控制算法、PID(比例-积分-微分)控制算法及模糊控制算法,得到这三种控制算法的中低速磁浮列车制动力特征曲线,进而对中低速磁浮列车的电磁涡流制动效能进行了深入分析。[结果及结论]对比仿真结果和试验实测结果,列车制动力的变化趋势几乎一致,由此可认为所推导的数学模型可信度较高。开环控制算法存在明显的超调,模糊控制算法较PID控制算法表现更佳。[Objective]Linear eddy current braking device is one of the key technologies for maglev trains,but this technology is still not mature enough.It is of great theoretical significance and application value to study the eddy current braking technology.[Method]A model of linear eddy current braking device for medium-low speed maglev trains is established,and the formula for calculating the total eddy current braking force F is derived.To verify the deceleration efficiency of the designed eddy current braking device,an eddy current physical device is developed and a test bench experiment is carried out.A model of electromagnetic eddy current braking torque control system is established,and based on open-loop control,PID(proportional-integral-derivative)control,and fuzzy control three control algorithms,the respective medium-low speed maglev train braking force characteristic curves are obtained.The electromagnetic eddy current braking efficiency of medium-low speed maglev trains is then thoroughly analyzed.[Result&Conclusion]Comparing the simulation results with the experimental measurements,the changing trends of the train braking force are almost identical,indicating a high credibility of the derived mathematical model.The open-loop control algorithm exhibits significant overshooting,while the fuzzy control algorithm outperforms the PID control algorithm.
