The deepwater drilling riser is important equipment for deep-sea oil and gas production. The recoil movement of the riser after emergency disconnection has potential collision risk to drilling platform and subsea wellhead. In this paper, takagi-sugenod (T-S) fuzzy modeling and fuzzy sliding mode recoil control for riser-tensioner coupled nonlinear systems are studied. First, the fuzzy model of riser-tensioner nonlinear recoil system is presented using the T-S fuzzy modeling method. Second, the design method of fuzzy sliding mode recoil controller with memory is given, and the existence condition and solving method of the fuzzy sliding mode recoil controller with memory are obtained. The simulation results show that the fuzzy sliding mode recoil controller with memory proposed can effectively suppress the recoil response amplitude of the riser and improve the safety and reliability of emergency disconnection of the drilling riser.
