摘要
运用轨道车辆信息估计技术,获取轮对状态和未知线路特征信息,其中估计的左右轮转速和线路信息,实现速差反馈导向控制;估计的摇头角,用于稳定性集成控制,替代一系纵向悬挂。最后,使用典型的独立车轮轻轨车辆模型对估计与集成控制技术仿真验证,研究结果表明:基于信息估计的集成控制,轮对导向性能均非常优秀,轮缘不贴靠钢轨,摇头角/冲角小;集成控制系统对电机的功率需求最大不足60W,电机力矩需求约为牵引电机额定转矩的1/5,实际牵引电机可以满足。
An information estimation technique for rail vehicle is used to get the wheelset station and unknown track characteristics.Using the estimated wheel rotating speed and track curvature,the active steering control via the speed differential feedback is realized;based on the estimated yaw angle,the integrated stability control is used to replace the longitudinal suspension.Finally,the typically LRV with independently rotating wheels is applied to verify the proposed methods.The results show that the integrated control technology based on the estimation information are very good in steering performance,flange is not close to rail,yaw/attack angle is small;the maximum power demand is 60 W,and torque demand is about 1/5 of the rated torque for each traction motor.The traction motor can completely satisfy the demand.
