Özet:

 

A new model-free approach was investigated to control two moving   aps and a T-foil of a fast ferry traveling  in the head sea. Considered as a highly perturbed system, fast ferries in sea waves suffer from the undesirable effects  of pitch and heave motions causing severe vertical accelerations that lead to the discomfort of passengers who then  experience seasickness. To appropriately control this multivariable system, a model-free control strategy was adopted.  An augmented PD controller with compensating terms resulting from an online identification of an ultralocal model of  the system was designed. Relying only on input{output data and using online numerical differentiation based on a fast  estimation technique, a nonphysical model was designed and continuously updated to capture all the unknown system  dynamics, uncertainties, and perturbations. The resulting controller, known as an intelligent PD (iPD) controller, has  been proven to be of a reduced design complexity but able to cope with the system's changing characteristics under  high perturbations. The robustness to parameter variations was analyzed and compared to a classic PD controller's  performance. The results showed that good reductions in the system's vertical motions and seasickness were obtained  with a low computational cost. Moreover, the iPD successfully exhibited very robust behavior based on its model-free  property when changing the system parameters and the operating velocity.
