| titleOfInvention | System for estimating height of sea wave based on attitude information of ship |
| abstract | The invention belongs to the field of estimation on attitude information of a ship, and in particular relates to a system for estimating height of sea wave based on attitude information of the ship. The system comprises an unscented kalman filter, a sea wave disturbance estimator, a sea wave height estimator, and an acceleration sensor of a measuring system on the ship, wherein an inertia gyroscope measures the attitude information of the ship, the sea wave disturbance estimator receives the controlled quantity acting on the ship and simultaneously receives an estimated value of the hydrodynamic coefficient output by the unscented kalman filter, so as to obtain the sea wave disturbance force and force moment estimation sequences output by the sea wave disturbance estimator, the sea wave height estimator receives the sea wave disturbance force and force moment estimation sequences to obtain the sea wave height estimation sequences. The system can well solve the problems that the parameters of kinematic equation of the ship are unknown and uncertain and indirectly solve the sea wave height by utilizing the sea wave disturbance acting on the ship and derived by the attitude of the ship in an inverted mode, so as to achieve high computational accuracy. |
