Abstract

In this paper, we propose simultaneous control which improve in transient state performance of mechanical parking facilities through simultaneous control of PLC and inverter. In conventional mechanical parking facilities, it is controlled only by PLC, and it is more likely to generate over-currents in induction motors, and the ride comfort is reduced due to wear and damage caused by friction on the brake pads, and the life is shortened. To improve this problems the application of control techniques through simultaneous control of PLC and inverter prevents over-currents in induction motors, protects brake pads, improves ride comfort, increases control and ensures safety. We verify its validity by applying the proposed control method via simultaneous control of PLC and inverter to a mechanical parking facility.

본 논문에서는 과도 상태 성능 향상이 있는 PLC와 인버터의 동시 제어기법을 제안한다. 기존 기계식 주차설비에서는 PLC만을 활용한 제어 방식이어서 유도전동기에 과전류를 발생시킬 확률이 높고, 브레이크 패드에 마찰로 인한 마모와 손상으로 승차감이 낮아지고, 수명이 단축된다. 이를 개선하기 위해서 PLC와 인버터의 동시 제어를 통한 제어 기법을 적용한 경우 유도전동기에 과전류를 방지하며 브레이크 패드를 보호하고, 승차감 향상, 제어성 상승과 안전성을 확보한다. 제안한 PLC와 인버터의 동시 제어를 통한 제어 방식을 기계식 주차설비에 적용하여 그 타당성을 검증한다.
