초록

본 논문에서는 고정된 역간 거리를 정해진 운전 시분내에 주행에너지를 최소화하며 주행하는 열차의 특성을 파악하고 수학적으로 모델링한다. 도시철도차량 자동주행에 일반적으로 사용되는 PID제어기 대신 목표값에 추종하면서도 자동 주행 중 소비에너지가 최소화되도록 최적제어기를 사용하여 철도 차량를 모델링하였으며 실제 동일한 운행조건하에서 설계한다. 실제 선로 조건을 적용하여 별도의 차상장치나 선로주변시설 없이도 자동운전 중 주행에너지를 최소하여 주행에너지를 절감하고자 한다. 따라서 8호선 실 노선 구간별 운전시분 내에서 실측 데이터 분석을 위해 직선구간/구배구간/곡선구간 등 구간을 선정하고 그 구간에서 열차의 운행패턴에 따라 에너지를 절감하는 열차운행을 방법을 제시하였다.

In this paper, Minimize driving energy for operation within a defined distance yeokgan fixed time-resolved and determine the nature of the train is traveling, and to model mathematically. Urban rail car cruise in general by the PID controller is used instead of automatically tracking a target value while traveling in energy consumption to be minimized by using optimal control model railroad charyangreul was designed under real operating conditions the same. The actual track conditions apply to the minimum value or a separate listing of cars around the track facility without a driving energy of the automatic operation and to reduce the driving energy. Therefore, actual route chosen straight line 8 / gradient segment / curve for the measured data analysis, such as sections within the city-minute drive each section and presented how the trains to save energy, depending on the pattern of the train station in the region.
