Zero-speed fin stabilizer is applied to reduce the roll motion of ships at zero speed. This paper aims to explore the control strategy of zero-speed fin stabilizer through a composite method of theoretical analysis, simulations and tank tests. The hy

ZnO varistor ceramics with a high potential gradient, as well as a high nonlinear coefficient, were reported and analyzed in this paper. With the use of nano-sized ZnO powders, the average grain size was reduced to about 2.6 μm, which successfully r

Fin stabilizers have been widely used to reduce the roll motion of ships at medium-high velocities. However, the anti-rolling efficiency of the traditional fin declines rapidly as the speed of the ship decreases. To enable more efficient use of fin s

The output and input nonlinear of fin stabilizer at zero-speed with its uncertainty has led to complicated control structure and undesirable stabilizing effect. The drag-based force mechanism different from lift-based fin result in PID controller wel

The hydrodynamic of zero-speed fin keeps no longer approximate ratio relationship with fin angle, but has a memory nonlinear mapping with the fin angle, angular velocity and angular acceleration, besides its nonlinearity and uncertainty of ship roll

This paper considers an active control system that reduces pendulation of suspended loads for the underactuated characteristic of the three-dimensional davit system. The dynamic model is established with the Lagrange equation and the anti-swing contr
