Abstract

Elevator power consists of power consumption in stand-by and in service. This paper designed a fuzzy controller saving stand-by power of elevators in a way that calculates the adequate number of elevators by the variable traffic volume of passenger and then powers off elevators being out of service. Also, the fuzzy controller was designed to minimize a increase of the average passenger's waiting time by the limited number of elevators in service. When the fuzzy controller designed in this paper was applied to the group elevator experimental device, The passenger's waiting time increased approximately 7.5%~9.5%, While the stand-by power saving is expected to be about 675KWh a day per unit and about 236.6KWh a year per unit.

엘리베이터의 전력은 대기 시에 소모되는 전력과 운행 시에 소모되는 전력으로 분류할 수 있다. 본 논문에서는 변화가 많은 승객의 교통량에 적절한 운행 대수를 계산하고 운행하지 않는 엘리베이터의 전원을 차단하여 엘리베이터의 대기전력을 저감시키는 퍼지제어기를 제안하였다. 또한 엘리베이터의 운행대수 제한에 의한 승객의 평균 대기시간의 증가도 최소화 하도록 퍼지제어기를 설계하였다. 본 논문에서 제안된 퍼지제어기를 그룹 엘리베이터 실험장치에서 실험하였을 때에 승객의 대기시간이 약 7.5%~9.5% 증가하였고, 한 대당 하루 약 675KWh의 대기전력 저감과 한 대당 년 간 약 236.6KWh의 엘리베이터 대기전력의 저감이 예상된다.
