摘要
针对不确定性条件下轨道交通列车弓网接触力改善的问题,首次提出了一种基于区间二型模糊PID(IT2F-PID)的受电弓半主动控制方法。首先,建立了三元弓网半主动控制模型。其次,设计了IT2F-PID半主动控制器,并且与一型模糊PID(T1F-PID)和PID半主动控制器对弓网接触力的控制效果进行对比分析。进一步考虑受电弓存在模型不确定性和外部扰动的问题。最后,以DSA380型受电弓为对象进行仿真实验验证。实验结果表明:当列车运行速度为200 km/h和300 km/h时,相较于被动控制,IT2F-PID半主动控制算法作用下的弓网接触力标准差分别降低了18.21%和24.91%,能有效改善弓网受流质量。另外,与主动控制相比,设计的半主动控制器具有所需能量更少的优点,而且拥有更好的处理模型不确定性以及抗扰动能力。
Aiming at the problem of improving pantograph-catenary contact force of rail transit trains under uncertain conditions,a pantograph semi-active control method based on the interval type-2 fuzzy PID(IT2F-PID)was proposed for the first time.Firstly,a three-degree-of-freedom pantograph-catenary semi-active control model is established.Secondly,the IT2F-PID semi-active controller is designed,and the control effect of the pantograph-catenary contact force is compared with the type-1 fuzzy PID(T1F-PID)and PID semi-active controllers.The problems of model uncertainty and external disturbance of the pantograph are further considered.Finally,the DSA380 pantograph was used as the object for simulation experiment verification.The results show that:when the trains run at 200 km/h and 300 km/h,compared with the passive control methods,the standard deviations of the pantograph-catenary contact force under the IT2F-PID semi-active control algorithm are reduced by 18.21%and 24.91%,respectively,and the quality of pantograph-catenary current can be effectively improved.In addition,compared with active control methods,the designed semi-active controller has the advantages of less energy required for the outside world,and has stronger ability to deal with model uncertainty and anti-disturbance.
