Abstract

This paper relates to the electric braking, the permanent magnet synchronous motor vector control is suspended until the applied, and propose a new scheme by the controller in the observer to estimate the position and velocity using the Resolver speed detector. In addition, as a way to control the speed by braking torque at low speed, the pole of a stop just before the stop electrical braking. As a result, noise and dust abatement, consumption, reduction of the brake shoe increase the maintainability of comfort and energy use, enhances the effect of EMU performance improved sikyeoteum could see.

영구자석형 동기전동기에 벡터제어를 적용하여 정지시까지 전기제동을 하였으며, 속도검출기는 레졸바를 사용하여 제어기에서 관측자에 의한 위치와 속도를 추정하는 방식을 제안하였다. 또한, 정지직전의 극저속에서 속도에 의한 제동 토오크를 제어하는 방법으로 정지시까지 전기제동을 하였다. 그 결과 제륜자의 소모율 저감과 유지보수성을 증대시키고 소음 및 분진발생의 저감, 승차감과 에너지 사용효과를 향상시켜 전동차의 성능을 향상 시켰음을 알 수 있었다.
