In the process of operation, conduit rack offshore platforms are often subject to the coupling effect of time-varying loads such as wind, waves and currents, which generates vibrations that have a serious impact on the safety of conduit rack offshore platforms and their equipment. Active control is currently an effective method for vibration control of offshore platforms; however, active control is subject to the influence of sensors, controllers, actuators and other links, resulting in different degrees of time lag in the vibration control system of offshore platforms. This chapter proposes an overshooting hysteresis control algorithm based on the AMD-LQG active control system, which inputs the error signal into the overshooting hysteresis controller, and pre-processes the error signal by adjusting the phase and amplitude of the signal to improve the stability of the system and increase the response speed. The research provides a new idea for the active control of conduit rack offshore platforms under complex excitation in the ocean.
