摘　　要：磁浮控制系统是磁浮列车的重要组成部分,是保证磁浮运行的安全性和平稳性的关键部分.本文以PID控制器为研究对象,为了研究磁浮列车中悬浮控制的动态性能与控制参数的变化规律,建立了基于状态反馈的PID磁浮控制系统的数学模型,并通过多体动力学软件SIMPACK联合可视化仿真工具MATLAB/SIMULINK建立了耦合分析模型,进行了多参数的比较分析.系统讨论了单磁铁控制器在不同PID控制参数下,磁浮间隙和磁浮电磁铁加速度等监测控制量的变化曲线,并针对双向受力状态的不同,分别研究了具体工况下高速磁浮的竖向和横向控制性能.研究表明:本文所使用的高速磁浮控制系统模型,具有较强的抗干扰性和鲁棒性,控制性能优秀,其参数分析方法可为未来实际工程的建设提供技术支撑.Maglev train control system is an important part of maglev train. It is the key to ensure the safety and stability of maglev operation. This paper aims at investigating the PID control. In order to study the dynamic performance of suspension control and the change rules of control parameters in maglev train, the mathematical model of PID maglev control system was established based on the state feedback method. In addition, the coupling analysis model was established by using the multi-body dynamics software SIMPACK and the visual simulation tool MATLAB/SIMULINK. The comparative analysis of multiple parameters was carried out. This paper systematically discussed the change curve of the levitation gap and the acceleration of the single magnet controller under different PID control parameters. According to the difference between the bi-directional loading conditions, the vertical and horizontal control performances of the high speed maglev under the specific working conditions were also studied. This research showed that the high speed maglev control system has strong anti-interference and robustness properties.It had excellent control performance and could provide technical support for the future engineering practice.
