Popis: This paper addresses the dynamic modeling and active controller design of offshore structures subject to control delays and earthquakes. First, by considering the time-varying control delays and earthquakes, a delayed dynamic model of the marine structure subject to earthquake is established. Then, the asymptotic stability are ensured by some sufficient conditions and the \(H_\infty \) performance index of closed-loop system are derived, and the design scheme of an active damping \(H_\infty \) controller for the offshore structure is presented. The simulation results show that the vibration of marine structures caused by earthquakes can be effectively reduced through the designed control scheme.
