Abstract

In this paper, how to stop a moment to experiment with stop function, electric brake type scale model propulsion system is designed and fabricated by control of the braking torque is proposed. Scale model system for motor-driven, inertial load, the structure of the load for the motor and the inverter system was constructed with two sets of converters, the actual range of the rotational speed of the vehicle DDM experiments to be able to. In Additional, observer to estimate the rotor position and speed of using resolver, and the pole at low speed, speed detection methods have been developed. As a result of this study, first, stop the moment Second, the reduction of braking torque, and how to initiate the operation of the air brake blending by using the braking, improve braking methods that only use the electric brake to stop brought.

본 논문에서는 정지시까지 전기제동을 하는 축소모형 추진시스템을 설계하고 제작하여 실험하였으며, 정지순간 제동토오크의 제어방법을 제안하였다. 또한, 레졸바를 사용한 회전자의 위치와 속도를 추정하는 관측기에 의하여 극저속에서 속도를 검출하는 방법을 개발하였으며, 또한 정지순간 제동 토오크의 감소와 동시에 공기 브레이크의 동작을 개시하여 블렌딩 제동을 사용하는 방법과 비교하여, 정지시까지 전기제동만을 사용하는 향상된 제동방법을 제안하였다.
