摆式客车倾摆控制系统输入延迟补偿方法

运用在线检测信号作为倾摆控制系统参考信号的摆式列车,由于低通滤波会造成信号滞后.对滞后的补偿,目前主要是运用陀螺仪、轨道负荷分配差异方法.提出横向未平衡加速度信号预测法,来补偿由于滤波造成的加速度滞后,给出了建立参考输入信号的算法.研究表明：运用信号预测法,不必测出曲线超高及半径的具体值,可以不使用陀螺仪及轨道负荷检测装置,滤波可由软件或硬件实现,节约成本;对滞后时间不同的车辆,设置不同的启动阈值,不仅可保证倾摆的正确性,而且保证了控制参考输入信号的实时性.

Compensation for Input Postpone in Tilting Passenger Car''''s Control System

Tilting passenger train uses the on-line measuring signals, which is delayed from low-pass filtering, as tilting control reference signals. The compensation method of the delay includes gyro, and difference of track load distribution method. This paper presents a lateral unbalanced acceleration predicted signals method, a new compensation method which can build the reference signals. The research results show that it does not need to measure curve super-high and the exact value of radius by the gyro or the track loads measuring equipment when the prediction method is applied. The filter can be achieved by software or hardware. And the cost can be saved. Different startup values are set up to different time-delayed tilting cars. Not only the tilting preciseness but the real time is guaranteed.
