自20世纪70年代三相驱动的铁路车辆问世以来，电力铁路车辆中使用的功率半导体已从晶闸管变为GTO晶闸管和IGBT。在牵引电机控制方面，矢量控制已取代转差频率控制而得到广泛应用，无速度传感器矢量控制在商业列车上正处于试验阶段。利用轮轴速度信息对铁道车辆进行防滑重粘控制，取得了很大的进展。未来无速度传感器矢量控制的机车和电动车组应至少具有与有速度传感器的替代方案相同的粘着性能。本文提出了一种新型的无速度传感器防滑重粘控制方法。通过这种方法可以很容易地检测到小的车轮打滑。其性能可望达到带速度传感器控制的水平。列举了铁路车辆车轮打滑现象及防滑控制的特点，阐述了带速度传感器的防滑重粘控制的基本原理，介绍了新型无速度传感器防滑重粘控制的原理，并通过仿真验证了其基本功能。
Since the advent of railway vehicles with three-phase drive in the 1970s, power semiconductors used in electric railway vehicles have been changed from thyristors to GTO thyristors and IGBTs. As for traction motor control, vector control has come into wide use in place of slip frequency control and vector control without speed sensor is at a trial stage for commercial trains. Anti-slip and readhesion control of railway vehicles has greatly progressed by utilizing wheel axle speed information. Locomotives and electric multiple units with speed-sensor-less vector control in the future should have at least the same adhesion performance as that of the alternatives with speed sensor. In this paper, a novel anti-slip readhesion control without speed sensor is proposed. By this method small wheel slips can be easily detected. Its performance is expected to be as high as that of the control with speed sensor. This paper enumerates the characteristics of wheel slip phenomenon and anti-slip control for railway vehicles, explains the running test results that show basics of anti-slip readhesion control with speed sensors, describes an outline of the novel anti-slip readhesion control without speed sensor, and verifies the basic functions by simulation.
