A study on elevator control using micro-processor

Micro-processor를 이용한 엘리베이터 제어에 관한 연구

Elevator system requires position and speed control at the same time recently. The control device of existing Elevator system making hardware is simplified by using micro-processor that have been developed. In this papers, it consists of contactless logic circuit using miro-processor and digital components. This paper shows that as this system control voltage and frequency using PWM inverter at the same time, speed control is accurate, acceleration and deceleration is soft and passengers can be feel comfortably because speed change is a little during driving.
