Statistical Estimation of Rolling Angles of Ships

Journal of Zosen Kiokai, 1961
The irregularity of the natural phenomena e. g. sea waves is expressed by Rayleigh distribution in short times. In the course of time the mean of this distribution varies approximately according to the logarithmico-normal distribution, and so the whole distribution and that of the maximum values in some portions of time may be also expressed by this ...

Robust predictive control for anti-rolling path following of underactuated surface vessels using adaptive Kalman filter

International Journal of Advanced Robotic Systems, 2019
With the strong time-varying disturbances in wave fields, the large sway motion of underactuated surface vessels can be caused leading to the control performance reduction and large range of roll angle, such that a novel path following control with roll ...

Pedestrian Dead Reckoning with Low-Cost Foot-Mounted IMU Sensor

Micromachines, 2022
In this paper, we researched Pedestrian Dead Reckoning (PDR) with one foot-mounted IMU sensor. The issues of PDR are magnetism noise and accumulated error due to the noise included in acceleration and gyro data.
