重载列车优化操纵算法设计与仿真

文章针对电力牵引重载列车的运行特点,对重载列车的优化操纵问题进行了分析研究,设计了一种基于模糊预测和再优化的列车运行控制算法。该算法先使用模糊逻辑控制器产生操纵队列,预测列车未来一段区间的运行情况,然后对产生的操纵队列以安全、节能为目标进行反复优化。算法通过对操纵队列的有重合区间局部寻优来保证得到近似全局最优解。文章使用列车牵引计算模型对算法进行了仿真验证,结果表明该算法产生的操纵队列基本达到了重载列车运行要求。

Design and simulation of heavy haul train operation algorithm

In this paper, an algorithm based on predict fuzzy control and re-optimization have been proposed after analyzing characteristics of heavy haul train operation. The algorithm has two steps. Firstly, the queue of operation is produced by fuzzy controller, which reflects the condition of train in the front zone. Then the queue of operation is optimized again and again for the safe and energy-efficient requirements. The man-made optimized zones are partly superposed. So the operation nearly reaches the whole optimized result. The simulation shows that operations produced by the algorithm meet requirements of heavy haul train.
