Ship roll damping control
The technical feasibility of roll motion control devices has been amply demonstrated for over 100 years. Performance, however, can still fall short of expectations because of difficulties associated with control system designs, which have proven to be far from trivial due to fundamental performance limitations and large variations of the spectral characteristics of wave-induced roll motion. Thi...
متن کاملShip Roll Motion Control
The technical feasibility of roll motion control devices has been amply demonstrated for over 100 years. Performance, however, can still fall short of expectations because of deficiencies in control system designs, which have proven to be far from trivial due to fundamental performance limitations. This tutorial paper presents an account of the development of various ship roll motion control sy...
متن کاملAdaptive Robust Fuzzy Fin Stabilizer Design for Ship Roll Nonlinear Systems
This paper addresses the problem of designing fin control for the ship roll stabilization. A novel adaptive robust fuzzy control (ARFC) algorithm is presented for ship roll nonlinear system with unstructured uncertainties. In the algorithm, the Takagi-Sugeno type fuzzy logic systems are employed to approximate uncertain functions in the systems, and a systematic procedure is developed for the s...
متن کاملFuzzy Sliding Mode Control for Ship Roll Stabilization
A fuzzy sliding mode controller is proposed in this study for ship roll stabilization. Ship dynamic models usually contain large uncertainty. Sliding mode control is well known for its good robustness to large uncertainty. However, the required uncertainty bound is usually difficult to estimate. A fuzzy logic is designed here for the upper bound estimation of the uncertainty coming mostly from ...
متن کاملطراحی کنترل کننده غیرخطی مد لغزشی و H_∞ غیرخطی برای پایدارسازی حرکات چرخشی رول شناور در حال سکون مجهز به عملگر ژایرو
For stabilization of zero speed ships active anti roll tanks and gyro stabilizers are used. Because of anti roll tank limitations on working frequencies gyro stabilizers are proposed. A nonlinear model for ship is used to simulate hydrodynamic forces. Wave’s disturbances are considered as non-parametric uncertainty. A sliding mode controller is used for roll stabilizing. A nonlinear h infinity...
