摘要
高速列车采用电空复合制动,具有综合制动的特性。为求解高速列车准点运行的节能最优控制问题,将电力再生制动工况和空气制动工况从综合制动特性中分离,建立适用于描述高速列车节能控制的运动学模型;将列车牵引传动系统效率和电力再生制动能量利用率引入能耗函数,并应用庞特利亚金极大值原理分析实现高速列车节能最优控制的必要条件,得到完整的高速列车节能最优控制工况集,推导牵引恒速、电力再生制动恒速和综合制动恒速这3种恒速控制工况下最优保持速度与电力再生制动能量利用率、牵引传动系统效率之间的定量关系,从而提出能够满足高速列车准点运行的节能优化控制算法。通过案例仿真,验证了算法的正确性。
Electro-pneumatic brake with integrated braking characteristics is adopted for high-speed train.To solve the optimal energy-efficient control problem for the punctual operation of high-speed train,both the electric regenerative and pneumatic brake conditions are separated from integrated braking characteristics to establish a kinematics model applicable to describing the optimal energy-efficient control of high speed train.Meanwhile,the efficiency of train traction drive system and energy utilization ratio of electric regenerative brake is introduced to energy consumption function.Pontryagin maximum principle is applied to analyze the necessary conditions for the optimal energy-efficient control of high-speed train and a complete set of optimal energy-efficient control conditions for high speed train is obtained.The quantitative relationships between the optimal cruise speed（under the constant speed control conditions of traction,electric regenerative brake and integrated brake）and the energy utilization ratio of electric regenerative brake and the efficiency of traction drive system as well are also deduced.Accordingly,an optimal energy-efficient control algorithm for the punctual operation of high-speed train is proposed and its correctness is verified by case simulation.
