摘要
Abstract
In order to overcome the disturbance from the waves in AUV low speed motion in shallow water, a new type of nonlinear observer based on passivity principle is designed. The observer can estimate AUV' s low frequency motion signals and environmental disturbance force from the synthetical signals including the low frequency motion signals, high frequency motion signals and noise from the sensors. The nonlinear observer designed based on the nonlinear AUV dynamic equations overcomes the limitation of traditional Kalman filter based on linearization theory. The stability of the observer is proved by the Lyapunov methods and the simulation on a fully actuated AUV validities the observer.关键词
