高速列车制动及牵引自动控制研究

Traction and Braking Auto-Control of High Speed Train Systems

列车自动运行(ATO)系统的列车自动控制系统的重要组成部分。针对牵引和制动工况的不同工作机理,建立了列车牵引和电阻制动下的动力学模型,并采用非线性反步设计方法设计了相应控制器,以实现列车的速度和位置自动跟踪。理论分析和仿真结果表明,文中给出的反步控制器可以取得满意的高精度速度和位置跟踪效果。

ATO(Automatic Train Operation)is one of the most important units for train control system.A train dynamic model based upon different working mechanism during traction and braking phases is established.Control design for each phase is developed by using backstepping approach to achieve automatic position and velocity tracking.Theoretical analysis and simulation studies confirm that the proposed method is able to achieve satisfactory control performance in that high precision position and velocity tracking are ensured.
