摘　　要：８０年代中期由德国鲁尔大学Ｍ．Ｄｅｐｅｎｂｒｏｃｋ教授提出的直接自控制方法，经过ＡＢＢ公司工程师的后续开发，已经成功地用于干线内燃和电力机车，如奥地利联邦铁路的１８２２和瑞士联邦铁路的４６０电力机车上。与７０年代初期提出的磁场定向控制相比，直接自控制有着同样优异的动态性能，但实现更为简单，对电机参数变化不敏感、功率器件的开关能力可得到最充分的发挥．本文根据其在现代交流传动机车上的应用，从理论到实践对这种控制策略作了较为系统的介绍。Direct self control (DSC), which was proposed by Proffessor M. Depenbrock in Ruhr Universityin Germany in mid 80′s was developed afterwards by ABB engineers and applied successfully on main-line dieseland electric locomotives,e. g,electtic locomotive 1822 for O BB and 460 for SBB. Compared with field orientationcontrol proposed in the early 70′s, direct self control can achieve the same high dynamic Performances but inmuch simpler way. The motor parameter variation is no more critical and the switching capacity of power devicescan be given full play. On the basis of its application on modern AC drive locomotive,the author makes a systematic introduCtion of this control strategy from theory and implementation.
