摘要:
针对地铁列车运行过程的能量最优控制问题,根据列车的牵引/ 制动特性、线路限速、乘坐舒适性等要求建立列车运行过程线性二次型最优模型。为求解该模型,提出了一种时间域内状态变量离散化策略,将其转换为一个凸二次规划问题,并采用原—对偶预测校正内点算法获得所建立模型的近似解。算例计算和仿真结果表明,采用该线性二次型模型,可以在满足行车约束条件下实现地铁列车消耗能量的最小化。
Abstract:
It investigated the energy optimal control problem for metro train operation process and established a linear quadratic optimal model in according to the traction and brake capability, speed limits andpassenger comfort. A state variable parameterization strategy in time domain was proposed, hence the original problem is transformed into a convex quadratic programming problem, furthermore an approximate solution of the energy optimal control problem can be obtained by applying primal-dual predictor-corrector interior-point algorithm.Two simulation cases show that the proposed strategy and algorithm can reach minimal energy consumption for the metro train operation process.
