摘　　要：针对超级电容有轨电车节能驾驶问题,系统性考虑车辆牵引/制动特性、区间运行时间约束、线路坡度值变化、超级电容充放电能力等条件,提出一种基于极大值原理的最优操纵规则的改进动态规划算法。文章介绍了有轨电车运行系统模型,构建节能驾驶优化问题;基于极大值原理分析总结超级电容有轨电车节能驾驶工况集,结合动态规划思路构建速度轨迹状态空间;采用二分法迭代求解满足准点时间约束的节能驾驶速度曲线。仿真结果表明,改进动态规划算法比常规动态规划算法有更好的求解效率和求解质量,同时超级电容有轨电车的高再生制动利用率会提高电制动工况的使用时机,压缩惰行工况的使用时机。Focusing on the eco-driving for supercapacitor trams,considering traction/braking characteristics,trip operation time constraint,variable value of slope and power constraints of supercapacitor,a modified dynamic programming method was proposed with consideration the optimal manipulation derived from the maximum principle.Firstly,the system model was introduced,and an optimization problem was constructed.Then,eco-driving regimes of supercapacitor trams were analyzed based on the maximum principle.The state space of velocity trajectory was constructed integrating dynamic programming.Finally,the bi-section method was utilized to find optimized eco-driving speed profiles to satisfied the trip time constraint.Simulation results show that the better solve efficiency and quality can be obtained by the modified dynamic programming compared to the traditional dynamic programming.The high utilization rate of regenerative braking for supercapacitor trams increases the usage of electric braking condition and shrinks the usage of coast condition.
