유압식 엘리베이터의 제어특성에 관한 연구

In this study an elevator plant model is made with an electio-hydiaulic seivo valve and a single rod cylinder. A PID controller, a velocity feedback PID cantioller and a MRAC controller ate designed Experimental appaiatus including an elevator plant model and these contiollers are constructed. In case of experiment, external load which IS made with a hydraulic cylindel and a pressure control valve burdens varying load to the elevator plant model being driven with experiment, the control performances of three proposed control methods are compared.
