고속전자밸브를 사용한 서보인덱싱 시스템의 가변구조제어에 관한 연구 = A Study on the Variable Structure Control of Servo Indexing System using High Speed On-off Valves

다국어 초록 (Multilingual Abstract)

This study describes the application of the various structure control(VSC) concept for the position control of a servo indexing system using high speed on-off valves. The basic philosophy of VSC is that the structure of the feedback control is altered as the state crosses discontinuity surfaces in the state space with the result that certain desirable properties are achieved. The switching of the control function yields total(or selective) invariance to system parameter variations and disturbances, closed loop eigen value placement in time-varing and uncertain systems. The control scheme is derived, implemented and tested in simulation program. The control system schematics are given and simple results are shown for illustration. And the results of variable structure system for the servo indexing system using high speed on-off valves were compared each other when system parameter variation exists.
