Improvement of Tansient Response Characteristics of a Position Control Hydraulic Servosystem Using Observer (II) -Experimental Results Using Analog Observer-

본 연구에서는 비례제어하였을 때 정정한 시스템(K=1.0)과 진동 현상을 보이는 시스템(K=20)을 제어대상으로 설정한 후, 관측기의 상태변수를 이용하여 이들을 피이드백 제어하였을 때 응답 특성이 개선될 수 있는지를 조사하고자 한다.

The oscillatory hydraulic servosystem and the stable hydraulic servosystem under proportional control were feedback-controlled respectively using the estimated states of the observer. The observer was constructed in the analog computer and then it was interfaced with the real hydraulic servosystem to excute the experiment. As a result of experiment, the system that had been stable under proportional control responded more rapidly than before and the system that had shown oscillatory phenomenon under proportional control became stable with the same maximum acceleration and velocity that it had started under proportional control.
