| Abstract: | In this paper, a semi-actively tuned liquid column damper (TLCD) based on discrete-time neural networks sliding mode law is proposed to vibration control of fixed offshore platforms excited by earthquake. Firstly, the numerical model of a fixed offshore platform-TLCD system is given and its continuous state equation is set up and discretized. And then, the theory of neural networks sliding mode control(NNSMC) is simply discussed and the semi-active control strategy is established and implemented by NNSMC. Lastly, an actual platform, as the numerical simulated example, has been used to fully verify the effectiveness of this control method. |
| Keywords: | fixed offshore platform tuned liquid column damper neural networks sliding mode variable structure control semi-active control |
