RT Book, Section T1 The control of specific actuators for fast ferry vertical motion damping A1 Girón Sierra, José María A1 Katebi, R. A1 Cruz García, Jesús Manuel de la A1 Esteban San Román, Segundo AB The vertical motions of fast ships, which have a negative effect on comfort and safety, can be attenuated using moving actuators. There is the need of a control strategy to move the actuators in the most convenient way, considering several objectives. The paper considers this problem, studying a practical real example. Experiments with a scaled down replica of a fast ferry has been done, first for modeling purposes and second for control studies. Linear control shows serious application problems. Taking this into consideration, a nonlinear control approach is devised, with satisfactory results.
