작동시스템의 파라미터 불확실성을 고려한 강건 진동제어 = Robust vibration control considering parametric uncertainties of actuating system

다국어 초록 (Multilingual Abstract)

This paper present the design of a robust controller for a computer-controlled active vibration isolation system in the battle ship. Firstly, isolation system model is constructed considering the isolation structure equipped with precision electric devices actuator dynamic of a nonlinear hydraulic system. An active control system is designed based on sliding mode control theory regarding parametric uncertainties of the isolation structure induced by laden condition and varying parameters of the hydraulic system resulting from leakage, pressure drop of pressurized line and temperature-effected viscosity. Finally, the performance of the active isolation system is evaluated by simulation under certain disturbance condition with are transmitted from base structure of the battle ship induced by an under water explosion or firing of machine gun.
