This paper is concerned with delay-dependent robust H∞ control for an offshore steel jacket platform subject to wave force. By taking into account the variations of the structural natural frequency and damping ratio, and time-varying control delay, an uncertain time-delay dynamic modal of the offshore platform is established first. Then a delay-dependent robust H∞ control scheme is proposed to attenuate the wave-induced vibration of the platform. A delay-dependent robust H∞ controller is… CONTINUE READING
