【摘要】：低速磁浮列车利用电磁吸力支撑车体,相比轮轨列车具有噪音小、转弯半径小、爬坡能力强等优点。研究控制器输出饱和条件下悬浮系统的稳定性问题,可以避免由于电网电压约束而可能出现的失稳现象,提高了系统运行的可靠性。基于磁浮列车单点悬浮模型,使用电流-位置双环设计方法设计得到可稳定悬浮的控制算法。由于磁浮列车悬浮控制器的输出饱和环节,进一步提出了一种基于搜索极大椭球的控制参数优化方法,在不改变控制算法设计的前提下实现了参数优化。通过仿真和试验均验证了优化后的控制效果,有效指导了实际系统的工程调试。
[Abstract]:The low speed maglev train uses electromagnetic suction to support the car body, which has the advantages of less noise, smaller turning radius and stronger climbing ability than wheel-rail train. The stability of the suspension system under the condition of output saturation can be studied to avoid the instability due to the voltage constraint of the power system and the reliability of the system can be improved. Based on the single point suspension model of maglev train, a stable suspension control algorithm is designed by using the current-position double loop design method. Because of the output saturation of maglev train suspension controller, a method of optimizing control parameters based on searching maximum ellipsoid is proposed, which realizes the optimization of parameters without changing the design of control algorithm. The optimized control effect is verified by simulation and experiment, and the engineering debugging of the actual system is effectively guided.
