摘要: Speed profile optimization plays an important role in optimal train control. Considering the characteristics of electrical locomotive with regenerative braking, this paper proposes a new algorithm for target speed approximation. This makes following three contributions: First, it proves that under certain calculation precision, there is coast-brake switching region—not just point where should be switched from coasting mode to braking mode. very useful engineering applications. Second, analyzes influence on region and approximate linear relationship between regeneration efficiency. Third, presents average equivalent local steep sections. In addition, simplifies proof optimality smooth running non-steep track two steps. The effects energy consumption factors (optimal coast time) are systematically analyzed. Extensive simulations verify these points view demonstrate proposed approximation approach computationally efficient achieves sufficient accuracy.
