东京地铁16000系电动车组上采用了永磁同步电动机(PMSM)驱动方式,为以轴为单位实施精细的转矩控制提供了可能性,在空转、滑行再黏着控制方面是有利的。不过在改善该车滑行再黏着控制之前,仍沿用了传统的控制方式,不能充分发挥PMSM单独控制方式的优势。针对这一课题提出了新的算法,即在M车的4根轮轴中,设定前位第1轴用优先再黏着控制,以得到稳定的基准速度,余下的轴实施转矩优先的连续控制。运行试验确认了这种控制方式可改善加速度与乘车舒适度,具有各轴独立控制转矩的优点。
The PMSM drive on the 16,000-series EMU in Tokyo metro offers the possibility of implementing fine torque control in shaft units, which is advantageous in idling, coasting and re-adhesion control. However, to improve the car glide and then sticking control, still follow the traditional control methods, can not give full play to the advantages of PMSM separate control. Aiming at this problem, a new algorithm is proposed, in which, in the four wheels of the M vehicle, the pre-first axis is set to be pre-reattached with a preferential re-adhesion control so as to obtain a stable reference speed and the remaining axes are continuously preferentially controlled by torque . Operational tests confirm that this type of control improves acceleration and ride comfort, with the advantage of independent control of torque on each axis.
