Abstract

This paper proposes a torque predictive control for dynamic performance improvement of clamping force in electro-mechanical brake (EMB) for railroad cars. In general, pneumatic braking system (PBS) is used for railroad cars. It is sensitive depending on environmental changes and it has increasing idle running time because of slow dynamic response. Additionally, the PBS has low braking efficiency in case braking torque more than standard value is applied to the brake system such as emergency braking. In order to overcome these disadvantages of the PBS, the EMB is used for the railroad cars. The EMB for railroad cars has advantages that increasing the fuel efficiency and design flexibility because it is able to decrease vehicle weight of railroad cars and secure space for design. In this paper, control method for dynamic performance improvement of clamping force in EMB for railroad car is proposed. The effectiveness of the proposed control method is verified by the simulation results.

본 논문은 철도 차량용 electro-mechanical brake (EMB)의 클램핑 포스 과도응답 향상을 위한 토크 예측 제어 방법을 제안한다. 일반적으로 철도 차량에는 공압식 제동 시스템이 사용된다. 공압식 제동 시스템은 외부환경 변화에 민감하며, 과도응답 속도가 느리기 때문에 공주시간이 증가한다. 또한, 긴급 제동과 같은 기준 이상의 제동 토크를 인가하는 경우에 제동 효율이 낮은 단점이 있다. 이러한 공압식 제동 시스템의 단점은 철도 차량용 EMB 시스템을 적용하여 극복할 수 있다. 철도 차량용 EMB 시스템은 차량의 축중을 감소시키고, 설계 공간을 확보하기 때문에 연비 증가 및 설계 유연성 확보 등의 장점을 갖는다. 본 논문에서는 철도 차량용 EMB의 클램핑 포스 과도응답 향상을 위한 제어 방법을 제안한다. 제안하는 제어 방법의 타당성은 시뮬레이션을 통해 검증한다.
