Research of combined control scheme for fast catamaran motion control using t-foils and interceptors

Abstract

Fast catamaran oscillates in shortwave sea conditions due to its low length to beam ratio and relatively light weight. T-foils or interceptors are effective stabilizers for alleviating the pitch and heave motions of fast craft. This work designs a catamaran motion decoupling combined control system utilizing 2 T-foils and 2 interceptors, which can not only control the longitudinal motion, but also alleviate the roll motion of fast catamaran. Numerical simulation results show that the motion control system can satisfactorily improve seakeeping performance of fast catamaran.
